However, the present invention is not intended to be limited to the following embodiments, and the present invention includes all modifications, equivalents, and alternatives included within the spirit and scope of the present invention as defined by the claims. Please understand that The following embodiments have been selected to highlight specific inventive aspects or features of the invention.

  Throughout this specification, the same reference number represents the same element. When multiple elements are referred to as being “connected” or “coupled”, these elements may be directly connected or coupled, or there may be one or more intervening elements.

  As shown in FIG. 1, the proxy system 1 according to the present embodiment includes a terminal 10 and a proxy server 20. The proxy server 20 relays the request received from the terminal 10 to the Web server 30 and relays the response from the Web server 30 to the terminal 10.

  Each of the terminal 10, the proxy server 20, and the Web server 30 can be configured by a computer system or any other device capable of storing and manipulating data. For example, the terminal 10 may be a client terminal such as a mobile phone. As shown in FIG. 8, for example, the terminal 10 includes a CPU 81 that executes an operating system, an application program, a main storage unit 82 including a ROM and a RAM, and a nonvolatile memory. An auxiliary storage unit 83, a communication control unit 84 for controlling communication with the outside, a display unit 85 including a liquid crystal monitor and the like, and an operation unit 86 including keys for inputting characters and numbers and executing instructions Is provided. The proxy server 20 and the Web server 30 can also be configured by the same computer system as the terminal 10.

  As another form, the terminal 10 may be a portable information terminal, a portable laptop computer, a portable media player, a personal information manager, a home electric appliance, or other device having at least a data storage device. The proxy server 20 may exist in the same device as the Web server 30 or may exist in the same device as the terminal 10.

  For the connection among the terminal 10, the proxy server 20, and the Web server 30, any communication mechanism for performing communication can be employed. Examples include various wired communication protocols (Ethernet, token ring LAN, serial or parallel communication, etc.), various wireless communication protocols, packet communication, telephone, or any other communication medium. It is not limited. In the present embodiment in which the terminal 10 is a mobile phone, it may be a mobile phone line connection. In some cases, various encryption protocols can be used.

  Hereinafter, the configuration of the terminal 10 will be described. As illustrated in FIG. 1, the terminal 10 includes a terminal-side identifier assigning unit 105 that assigns an identifier to a response content (Web content) acquired from the Web server 30 via the proxy server 20, and the acquired Web content. The Web browser execution unit 104 to be displayed, the block specification unit 100 for the user to specify the portion to be cut out of the Web content displayed by the Web browser execution unit 104, and the specified portion is the user at the terminal When it is determined that the portion to be cut out is generated by being rewritten by a user operation, the rewriting determination unit 101 that determines whether or not the portion is to be cut out is generated as a target Web content. Terminal-side cutout unit 102 to be cut out from the content and content of the portion to be cut out or the portion to be cut out Composed of identification information (these are collectively referred to as "cutout partial data") and cut-out portion transmission unit 103 to be transferred to the proxy server 20, it contains.

  Next, details of the configuration of the proxy server 20 will be described. The proxy server 20 includes a proxy-side identifier assigning unit 205 that assigns an identifier to the response content of the request from the terminal 10 to the Web server 30, a cut-out partial receiving unit 200 that receives the cut-out partial data transmitted from the terminal 10, Based on the cut-out portion data, it is determined that the proxy server 20 needs to cut out a portion to be cut out and a cut-out determination unit 201 that determines whether or not the portion to be cut out needs to be cut out from the target Web content. In this case, the proxy-side cutout unit 202 that cuts out the portion to be cut out from the target Web content, the storage unit 203 that stores the content of the portion to be cut out, and the accumulated content of the portion to be cut out are updated in the Web server 30. Update confirmation unit 204 for confirming whether or not I am.

  Subsequently, the operation of the proxy system will be described with reference to FIGS. FIG. 2 shows a response to a request from the terminal 10 to the Web server 30, that is, an HTML document (Web content) acquired by the proxy server 20 from the Web server 30. The proxy side identifier assigning unit 205 of the proxy server 20 searches all the div tags in the HTML document of FIG. 2 and assigns the class attribute to all the div tags. Thereby, the HTML document (Web content) of FIG. 3 in which the class attribute is assigned to all the div tags is obtained. At this time, the proxy-side identifier assigning unit 205 obtains a hash value (in this case, “0x1234” and “0x5678” as an example) of the contents inside the div tag and calculates the class attribute as shown in FIG. Set values "proxyhash_0x1234" and "proxyhash_0x5678" as values.

  After the above processing, the web content is sent from the proxy server 20 to the terminal 10 and displayed by the web browser execution unit 104. When the web content is displayed by the web browser execution unit 104, the web content itself is rewritten by various scripts of the web browser. Therefore, the terminal-side identifier assigning unit 105 searches all div tags added on the Web browser and assigns the class attribute. At this time, the terminal-side identifier assigning unit 105 obtains the hash value of the contents inside the div tag (here, “0x90ab” as an example) and calculates “clienthash_0x90ab” as the value of the class attribute as shown in FIG. Set the value "."

  On the web browser, the web content itself may be rewritten by a script in accordance with the operation of the user of the terminal 10. For example, in FIG. 5, a div tag <div id = "interactive"> interactive data <div> is further added to the HTML document (web content) of FIG. 4 by a script according to the operation of the terminal user on the web browser. An example is shown.

  Next, a method for cutting out a part instructed by the user of the terminal 10 from the Web content will be described. FIG. 6 shows portions (1), (2), (3), and (4) that can be designated by the user. In response to an instruction from the user, the block specifying unit 100 acquires information on a portion to be cut out and transfers the information to the rewrite determining unit 101. In the following, a process when each of the parts (1), (2), (3), and (4) is cut out will be described.

  When the user specifies the part (1), the rewrite determining unit 101 calculates the hash value of the content inside the div tag of the part (1), and compares the obtained hash value with the value “0x1234” of the class attribute To do. Since the part 10 is rewritten in the terminal 10, the hash value obtained above does not match the value “0x1234” of the class attribute, and it is necessary to cut out the part 1 in the terminal 10. . Therefore, the rewrite determination unit 101 sends a cutout instruction for the part (1) to the terminal-side cutout unit 102, and the terminal-side cutout unit 102 cuts out the part (1) from the Web content and cuts out the cutout part (1). The data is sent to the transmission unit 103.

  Then, the cutout part transmitting unit 103 transmits the cutout part (1) to the cutout part receiving unit 200 of the proxy server 20. The cut-out part receiving unit 200 transfers the received cut-out part (1) to the cut-out determining unit 201, and the cut-out determining unit 201 sends the cut-out content itself from the terminal 10, and thus the proxy-side cut-out unit 202 Determines that it is not necessary to cut out, and transfers the cut-out portion (1) to the storage unit 203. Thereby, the cutout part (1) is stored in the storage unit 203.

  Next, when the user specifies the part (2), the rewrite determination unit 101 calculates the hash value of the content inside the div tag of the part (2), and uses the obtained hash value as the value of the class attribute. Compare with "0x5678". Since the portion (2) has not been rewritten in the terminal 10, the hash value obtained above matches the value “0x5678” of the class attribute, and it is not necessary to cut out in the terminal 10. That is, the rewrite determination unit 101 determines that the part (2) is not generated by being rewritten by a user operation, and sends the class attribute value “proxyhash_0x5678” of the part (2) to the cut-out partial transmission unit 103.

  Then, the cut-out partial transmission unit 103 transmits the value “proxyhash_0x5678” of the class attribute of the part (2) to the cut-out partial reception unit 200. The cutout determination unit 201 determines that it is necessary to cut out the part (2) in the proxy server 20 by receiving the value of the class attribute of the part (2) instead of the content of the part (2). The value is transferred to the proxy side cutout unit 202. The proxy-side cutout unit 202 performs the same processing as the proxy-side identifier assigning unit 205 described above, and generates a Web content to which the class attribute is assigned, thereby matching the class attribute acquired from the cutout-part receiving unit 200. The tag (the same as the part (2)) is acquired, and the content inside the div tag (that is, the part (2)) is transferred to the storage unit 203. As a result, the cutout part (2) is stored in the storage unit 203.

  Next, when the user designates part (3), the rewrite determination unit 101 starts the “class” of the div tag with “clienthash”. Rather, it is determined that the part (3) is not generated by being rewritten by a user operation. Then, the rewrite determination unit 101 sends the value “clienthash_0x90ab” of the class attribute of the part (3) to the cutout partial transmission unit 103.

  Then, the cut-out partial transmission unit 103 transmits the value “clienthash_0x90ab” of the class attribute of the part (3) to the cut-out partial reception unit 200. The cutout determination unit 201 determines that it is necessary to cut out the part (3) in the proxy server 20 by receiving the value of the class attribute of the part (3) instead of the content of the part (3). The value is transferred to the proxy side cutout unit 202. The proxy-side cutout unit 202 performs the same processing as the proxy-side identifier assigning unit 205 described above, generates Web content with a class attribute starting with proxyhash as a value, and further performs the same processing as the Web browser execution unit 104 Is performed, and a div tag (same as part (3)) that matches the class attribute acquired from the cut-out part receiving unit 200 is obtained by generating Web content with the class attribute starting with clienthash as a value, The contents inside the div tag (that is, the part (3)) are transferred to the storage unit 203. As a result, the cutout part (3) is stored in the storage unit 203.

  Next, when the user designates the part (4), the rewrite determination unit 101 does not include any one that starts with proxyhash or clienthash in the class attribute of the div tag. It is determined that the inner content is generated in response to a user operation on the terminal 10. Receiving this determination result, the terminal side cutout unit 102 cuts out the part (4) and sends it to the cutout part transmission unit 103.

  Then, the cutout part transmitting unit 103 transmits the cutout part (4) to the cutout part receiving unit 200 of the proxy server 20. The cut-out part receiving unit 200 transfers the received cut-out part (4) to the cut-out determination unit 201, and the cut-out determination unit 201 sends the cut-out content itself from the terminal 10, so that the proxy-side cut-out unit 202 Determines that it is not necessary to cut out, and transfers the cut-out portion (4) to the storage unit 203. Thereby, the cutout part (4) is stored in the storage unit 203.

  Note that the update confirmation unit 204 periodically inquires and confirms whether or not the content extracted by the proxy cutout unit 202 among the content stored in the storage unit 203 has been updated.

  As described above, it is possible to efficiently store the portion designated by the user in the Web content displayed on the terminal 10 in the proxy server 20 with less traffic.

  Each functional part on the terminal 10 may exist in the terminal 10 in advance, or may be provided from the proxy server 20, the Web server 30, or another server via a network.
