Unable to deal with some response in apps for ios.

Some responses can not be shown in fiddler,for example,i am analysising the package of 植物大战僵尸2(pvz2) for ios.it shows "400 .net error response headers...",but other app like burpsuite can deal with it well...

 

so i've to set the proxy of iphone to "192.168.1.2:8080" and the gateway of fiddler to "127.0.0.1:8888" where burp listens, then fiddler works ok...but it's also too complicated.

 

thx for your reply...(may u have a try?)

If I resend the same request locally as was captured in your failing capture, it works.

Looking at the data in the capture, we see:

X-HTTPPROTOCOL-VIOLATION: [ProtocolViolation] Incorrectly formed Request-Line. abs_path was empty (e.g. missing /).

This is a bug in the client. Your client is sending

   

   POST http://cloud.pvz2ios.popcap.com.cn HTTP/1.1\r\n

It should be sending

   POST http://cloud.pvz2ios.popcap.com.cn/ HTTP/1.1\r\n

Fiddler does not automatically fix this up for you. To fix it yourself, click Rules > Customize Rules.

Scroll down to

    static function OnBeforeRequest(oSession: Session) {

And add the following lines:

if ((oSession.HTTPMethodIs("GET") || oSession.HTTPMethodIs("POST")) && oSession.PathAndQuery == "") {
oSession["ui-backcolor"] = "orange";
oSession.PathAndQuery = "/";
}

 

Save the script and Fiddler will rewrite your requests to something the server will accept.
