In.
Decompression assembling module, receives the request for server-side, Blob object in request body is decompressed into
Cookie is assembled with request header, to restore request.
The beneficial effects of the present invention are: be different from the prior art, the present invention by the way that cookie is compressed into blob format,
And after backup, current cookie is emptied, when initiating request, server-side is sent by blob object, after decompression, with request
Head assembling, to restore request.By the above-mentioned means, the present invention can press Cookie in the case where compatibility existing browser
It is condensed to binary format, reduces server since Cookie transmits occupied bandwidth, improves to submit in slow network and request
Speed.
Detailed description of the invention
Fig. 1 is the flow diagram of embodiment of the present invention method one.
Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: Cookie is compressed into binary system, to be placed in request body, parsing
When, by unziping in request header, reduction request.
Fig. 1 is please referred to, the embodiment of the present invention one provides a kind of method that compression sends browser Cookie, comprising:
S1: the Cookie content in acquisition request, and gzip compression is carried out, it is converted into Blob object and is ready for sending；
S2: backing up in the variable that above-mentioned Cookie is defined to browser Javascript, and empties current domain name
Cookie；
S3:Javascript initiates request, the Blob object is placed in request body, and be sent to server-side；
S4: the Cookie being stored in variable is reverted in current domain name by Javascript；
S5: server-side receives the request, Blob object in request body is decompressed into Cookie, with request header group
Dress, to restore request.
It should be understood that Cookie is the text usually under some file directory in a browser before initiating to request
