In one embodiment, choice criteria module 304 comprises and determines that whether object is the one or more choice criteria of object of can filing.Can file to as if should (or being defined as) be included in the object in the file.Judge the object of quoting in the webpage according to choice criteria, to determine whether they are the object that can file.The example of choice criteria comprises the full-size of object and the type of object.For example, choice criteria module 304 can comprise that the object that can file should have the standard less than the size of 3k byte.Another standard can be that the object that can file must be an image file.

In one embodiment, the big little module 306 that files is determined the target sizes of filing.The big little module 306 that files can be determined the target sizes of file by the size of determining webpage.In one embodiment, the size of webpage comprise the object of quoting in the webpage size and.In another embodiment, the size of webpage comprise the size that is increased to the object of quoting in the webpage and the size of html file of webpage.

In one embodiment, the big little module 306 that files is made as the target sizes of filing the mark of the size of webpage.In one embodiment, target sizes is 1/4th of a webpage size.Most traditional web browsers are configured to open and reach four and be connected with the web server time.As a result, will cause by creating the decreasing returns (diminishing returns) of the performance benefits that realizes of filing greater than 1/4th file of webpage size.In another embodiment, target sizes is the number percent of the whole size of the object quoted in webpage.In another embodiment, target sizes is the part of the size of webpage, and this part can comprise ratio, number percent or the tolerance of form in addition, makes the file that the generates size less than webpage.

In one embodiment, the priority of the filed object of quoting in object priority discriminating module 308 definite webpages.The priority of object can be distinguished standard module 310 from object priority and determine by object priority differentiation standard.Determine the order of the filed object in the file by object priority discriminating module 308 definite priority.Filed object order with higher priority is before the filed object with lower priority.For example, the filed object of the form of definition in the webpage can be assigned with than the priority by the filed object Geng Gao of the image construction in the form.Because the filed object of definition tables has the priority higher than image, the filed object order of definition tables is before image.Priority by distinguishing the object that can file and to its ordering can be placed the filed object of decapsulation by can file object in decapsulation the time, more effectively presents the webpage that files and optimize.

In one embodiment, object priority is distinguished standard module 310 and is comprised that one or more object priority distinguish standards, and it determines the priority of the object quoted in the webpage of optimizing that files.Object priority differentiation standard relates to the filed Properties of Objects of quoting in the webpage of optimizing that files.For example, in dom tree before the lower object, this can improve presenting of the page with object order higher in the dom tree, because before the object of the object institute subordinate that removes from file can be used, the object that should remove from file can not present.Therefore, in one embodiment, the hierarchical level in the dom tree of the object that can file is that object priority is distinguished standard.For example, the filed object with high relatively hierarchical level (meaning from the less relatively stride of the root of dom tree) can have higher priority than the filed object with low relatively hierarchical level (meaning from the more relatively stride of the root of dom tree).As a result, the filed object order with higher priority in filing, make its decapsulation and present morning more.

Because same cause, in another embodiment, object priority is distinguished standard can comprise the number that derives from object in the dom tree.For example, the filed object with derivation object of big relatively number can be assigned with higher priority than the filed object of the derivation object with relatively little number.The result of this standard is the improvement about the possibility that can use at the object that removes from file that derivation can be filed before the object, prerequisite (prerequisite) can be filed.

When filing object minimum, can realize that the maximum of performance improves.Therefore, in one embodiment, the size of the object that can file is that object priority is distinguished standard.For example, if total size of the object that can file surpasses the file size of determining by the big little module 306 that files, then less filed object can be assigned with the priority higher than big relatively filed object.As a result, less filed object will be included in the file to improve the performance of filing.Big relatively filed object limits and may not be placed in the file owing to size.

Fig. 4 diagram be used to the file embodiment of filed object 404 of the dom tree 402 of the webpage optimized and the ordering that is used to file.Dom tree 402 can be included in a plurality of object 412-422 that arrange among the hierarchical level 406-410.Dom tree 402 is expressions of the relation between the object 412-422 in the webpage optimized of object.Object in the rank 2408 depends on the object in the rank 1406, and the object in the rank 3410 depends on the prerequisite object in the rank 2408 etc.For example, the object 2416 in the rank 3410 depends on the object 1414 in the rank 2408.

In one embodiment, can not suitably be presented in the webpage of optimizing that files, be presented in the webpage of optimizing that files up to the prerequisite object than the object in the low level.For example, object 1414 can be the form in the webpage of file optimizing, and the image of object 2416 in can the form of indicated object 1414.Because the image of object 2416 is defined as in the form of object 1414, so it can not be presented in the webpage of optimizing that files before form presents.

As the result of these dependencies and other consideration, can distinguish priority by object priority discriminating module 308 by the filed object of selecting module 204 to select and also sort as the filed object 404 of ordering.For example, Object Selection module 204 can determine that object 1414, object 3418, object 4420 and object 5 satisfy a group selection standard, and specifies these objects as filing object.Object Selection module 204 can also determine that object 2416 does not satisfy a group selection standard, and for example, object 2416 may have the size greater than threshold value.

Selecting module 204 can also be the filed object 404 of ordering with the object order that can file.Object priority discriminating module 308 can be distinguished the standard sorted object that can file according to object priority.For example, object 1414 and object 4420 since they in dom tree 402 in the relative high position at rank 2408 places, can be assigned with high priority.Object 1414 can be assigned with the priority higher than object 4420, because object 1414 has than object 4420 more subordinate objects.As a result, in the filed object 404 of ordering, object 1414 can sort before object 4420.
