Eric,
I have already written a C# extension that loads in a Excel document
and compares the URL's in the excel document to the URL's fired in
fiddler. So I have a little bit of knowledge of how to tie into the
fiddler session list and what not.
My question is there any way, when a page loads to search through the
pages source text and replace certain lines in it, then continue
loading the page with the updated text? I have read the thread on
"injecting tags to the HTML", and have stalked around the cook book. I
tired to take the code form the injecting tags thread but still wasn't
able to get/find and replace the pages code. Some of the cookbook code
sample seemed to have promise, but none that I used worked for what I
was trying to doing.
After watching the video I realized that I could use the AutoResponder
to do this, but it's of some importance that the page I am looking at
is the current live code with a certain line of text switched. I feel
the answer is a method call that I am missing, in time I am sure I
would stumble on the answer myself I was just wondering if you have
any insight for me moving forward.
If it helps I am currently using a different proxy for filtering the
HTML code (Proxomitron) to accomplish my task. I would like to just
use fiddler for this instead of having 2 proxies running at the same
time.
Thanks in advance,

Yes, you can easily replace content in pages. What sort of text are
you trying to replace, with what other text? Are you using
FiddlerScript or a C# extension?

The extension I currently have is written in c#. I am switching page
groups that exist in JavaScript tag calls. For example :
<body>
...
<script type="text/javascript">someFunction
("addContent","PG=SomeGroup",sizeH,sizeW);</script>
...
</body>
I would like to be able to find "SomeGroup" and swap it with
"SomeOtherGroup"

Did you try using:
if (oSession.HostnameIs("www.bayden.com") &&
oSession.oResponse.headers.ExistsAndContains("Content-Type","text/
html")){
oSession.utilDecodeResponse();
oSession.utilReplaceInResponse('SomeGroup','SomeOtherGroup');

Thank you Eric!
I did try to use that before, but it didn't work. You confirming that
was the code I needed prompted me to look where i was putting the
code. That is where my error was. I now have it working by putting the
code in the correct method.
public void AutoTamperResponseBefore(Session oSession) {}
The reason I was getting an error is because I was trying to change
the code before I even got the response from the page. /facepalm.
Thanks again Eric for the tool and the help!
