The relay / protocol conversion means 20 performs dial-up connection processing (step D1), converts communication information from the computer 1 into an IP protocol format (step D2), and stores the access destination URL and directory in the web server processing means 23. User file access means 25
If A (step D3), the means is activated.

If the received request is a registration or update of a transfer operation specification, the user file access means 25A transmits the transfer specification template 251 and the user A area 28A.
Is returned to the computer 1 (step D5).

The received transfer operation designation is entered in the user A area 28.
A is registered / overwritten on A (step D6). If the transfer operation designation is upload (step D7), a file to be continuously uploaded is acquired and stored in the user A area 28A (step D8). Then, display data and a procedure for prompting the disconnection of the line are returned.

Next, referring to FIG.
Will be described. The file transfer means 26 periodically checks the transfer operation designation of each user area. The transfer operation specification 283 and the execution record 282 are read from the user A area 28A (step E1). If there is a transfer operation specification corresponding to the date and time at that time, and there is no execution record within the transfer cycle, the destination URL of the transfer operation specification 283, Imports the file name, authentication information, and transfer direction, logs on to the destination, and executes file transfer.

For example, if the transfer cycle and the due date are designated every Friday, it is first checked that the current day is Friday, and if it is Friday, the file transfer is started if there is no execution record for the week. . If the transfer cycle and time zone are daily and late at night, the file transfer is executed if the time at that time is midnight and there is no execution record of the day.

Here, if the date and time zone are not specified, the transfer is started under the condition that there is no execution record in the transfer cycle (step E2).

First, an IP connection is made to the destination URL, authentication information is transmitted, and the user logs on (step E3). If the transfer direction is upload, the target file is read from the user A area 28A, the file is transferred to the destination URL, the success or failure of the upload is received from the destination URL, and the execution record 282 is updated including the success or failure and the execution date and time. If the other party cannot obtain authentication and cannot log on, the fact is recorded in the execution record (step E5).

If the transfer direction is download, the destination U
The RL is requested to transmit the target file, the target file is received and stored in the user A area 28A, and the user A directory 281 is updated. In addition, the result of the normality check of the received file data is recorded as download success / failure information along with the file name and the storage date and time, and an execution record is left (step E).
6).

Next, the operation in the case where the transfer operation designation has been registered and updated and the file download from the target URL or the upload to the target URL has been designated will be described with reference to FIG.

The browsing processing means 10 determines whether the destination URL and the file name are registered in the URL conversion information 101A (step C2), and determines the request content and the transfer direction since the registration has been performed (steps C7 and C9). If the file is to be downloaded, the access destination URL is converted to the user file access means 25A.

The user file access means 25A reads out the file X284 from the user A area 28A and returns it (step D11 in FIG. 7), which is downloaded by the browsing processing means 10 (step C10).

If the file is to be uploaded, the access destination URL is converted into the user file access means 25A and the next transfer file data is transmitted (step C1).
1). The user file access means 25A stores the received next file data in the user A area 28A (step D12 in FIG. 7).

In this way, if the operation specification is passed to the file transfer means provided in advance in the provider server and the latest file is periodically downloaded from the target site by changing it, access is concentrated. It is possible to download fresh file contents from the provider's server without connecting to the target server at the same time.

If a file is downloaded instead of browsing a homepage to which access is always concentrated, it is possible to browse offline after downloading without worrying about time.

[0072]

As described above, according to the file transfer method and the transfer method of the present invention, since the user transfers the file to the server where the access is not concentrated, the file transfer time is shorter than the file transfer to the server where the access is concentrated. Has the effect of shortening. Also, it is possible to avoid an increase in telephone line usage fees.

In the second embodiment of the present invention, since the file transfer means and the server for downloading the files by the procedure are always connected to the Internet, the transfer cycle and time zone for specifying the operation to the file transfer means are appropriately set. Setting to has an effect that the file contents with good freshness can be downloaded.
