How to handle a HTTP Request with gzip, deflate headers

[mary]

Hi!

Please, I need your help to handle decompression html page. Here is my code

if I send the following to in my request

$oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
$oHTTP.Open("GET", "http://www.stylephreak.com/index.php/archives/2004/08/standard-forms/")

[b]$oHTTP.SetRequestHeader("Accept-Encoding", "gzip,deflate")[/b] ; to get a compressed html page

$oHTTP.Send()

And then the Content-Encoding header in the response is 'gzip' or

'deflate'. How can I uncompress the content?

thinks a lot

Never done work with it personally, but here are some links that may help you from a google search-

I suppose you're looking for something more elegant than 1) save the response to a file, 2) inflate the file with gunzip?

o? They seemed to resolve exactly what you asked in the thread (using perl but same concept)

or is this not applicable?

the solution is given for perl with an embeded perl decompression library. Autoit have not a similar library

this solution needs a lot of disk access specially when you send many httprequest

Hi, I am interested in this too. Did you ever find a good solution? thanks.

Ok, I have a solution.

First, I modified InetGet (or _InetGetPro) so that it could retreive binary data

Then, I recompiled zlib.dll (zlib 1.2.3) so that the uncompress export could accept a variable zMode, which specifies gzip or zlib compressed data.

After amking the proper dll data structures, it's not too hard to do. Included in the zip file is the modified _InetGetPro and zlib1.dll, with header info.

Also, perhaps most importantly, I included a working example showing pure memory gzip http download and decompression, and a file gzip access example.

I can't post this in the example scripts section for some reason, it says I'm not allowed.. so here it is:

gzip_binary_InetGet.zip

Enjoy, and I appreciate your feedback.

Hmm i can't get it to work It crashes and gives an error at:

INetPro.au3 (194) : ==> Subscript used with non-Array variable.:

ElseIf $ai_ICU[0] = 0 Then

ElseIf $ai_ICU^ ERROR

Anyone know if there is a better solution or a resubmit of the zip file? The URL no longer works ;\
