Fiddlercore autoresponder issue

[asia]

I want to make a c# console application for intercepting the https connection to a server and return a local xml file as responcemy code is Fiddler.FiddlerApplication.BeforeRequest += delegate(Fiddler.Session oS)
{
if (oS.url.Contains("test.com"))
{
oS.bBufferResponse = true;
oS.utilCreateResponseAndBypassServer();
}
};

Fiddler.FiddlerApplication.BeforeResponse += delegate(Fiddler.Session oS)
{
oS.utilDecodeResponse();
oS.LoadResponseFromFile("file.xml");
};
But it doesn't seem to work, I get connection error. Any ideas?

You need to handle CONNECT tunnels specially.

Thanks for the reply but i still dont get it.

your link contains this, assuming i understand the first part how do i replace the return a session with return a specific file ? can you give me a code example ? cheers

Fiddler.FiddlerApplication.BeforeRequest += delegate(Fiddler.Session oS)
{
if (oSession.HTTPMethodIs("CONNECT")) { oSession.oFlags["X-ReplyWithTunnel"] = "Fake for HTTPS Tunnel"; return; }
if (oS.uriContains("replaceme.txt"))
{
oS.utilCreateResponseAndBypassServer();
oS.responseBodyBytes = SessionIWantToReturn.responseBodyBytes;
oS.oResponse.headers = (HTTPResponseHeaders) SessionIWantToReturn.oResponse.headers.Clone();
}
};

There are several ways to achieve the task of returning a specific file. The simplest would be to set the oS.oFlags["x-replywithfile"] flag to the target filename.

Alternatively, you could manually fill responseBodyBytes and the oResponse.headers based on whatever you want.
