I want to test input validation of all WebForm fields for any given field,  and not have to breakpoint and manually change values for each of the fields,  and then be able to view the results pages.  

Is this feasible with Fiddler? 

Thanks 

Is it possible to get older versions of Fiddler ?

I've been very happy until I upgraded.

Whenever Fiddler is running my connection is lost and debugging is impossible. When I poke around with the connection settings, I can get some connectivity, but HTTPS traffic is broken and not debuggable.

I don't have time to poke around and f$k around with settings which have changed or debug an application. It just worked so I'd like to revert or abandon.

The fact I need to sign up to be able to post here is also a annoyance: I KNOW you'll spam me with your other products and idiot newsletters for products I'll search for when and if I need them. I've been happily using fiddler without being annoyed or being spammed since 2003 and wish to continue to do so.

Firefox Fiddlerhook: What is the difference between "Use Fiddler automatically" and "Force traffic to Fiddler"?

If you install fiddler it will completely screw up google.

Hey all, I've played around with the Timeline and read through the knowledgebase page, http://docs.telerik.com/fiddler/knowledgebase/timeline.

I still can't seem to discover how to get actual times in milliseconds to show. I see the scale divided into 1s increments but nothing more granular. Anyone know the secret here? I can't imagine that functionality isn't in there someplace with all the other sophistication. Thanks!

I've downloaded a couple of extensions to check that I'm doing it right, but it doesn't seem that I can get Fiddler2 to recognize that the AustralianImages.dll file is actually a valid extension. I place it in the %USERPROFILE%\Documents\Fiddler2\Scripts folder, with other extensions, but while those other extensions load, this one doesn't.
I can't see any log or other information telling me why. Are there any obvious things I'm missing, or any steps I should take to troubleshoot this - or is it simply possible this sample no longer works?

Hi,

I'm trying to use a script for the action on an autoresponder, but I cannot get it to  work, and I cannot really find any information on how to do that. Is there some information around, or should I try to get the book?

/Pär

I thought it could, but cannot get it to do anything.

We're running Fiddler2 on the WCF 4.5 client side of a Java web service, Windows 7, Soap.

When I turn capturing on and send a request from my client app, I'd like to see what is actually being sent to the service including the Soap envelope and any request headers.  My problem is that the headers the service is expecting do not match the headers I'm sending, particularly the Content-Type, but I have no view of the headers so I can't tell what I'm sending.

I do see a file captured, but what's in it is meaningless to me.  When I open the Raw tab I see the mish-mash below.  Either it tells me what I already know, or nothing at all, but hasn't anything to do with the soap message or headers.  If I open the Headers tab it's just more garbage.  I can't even tell if it's looking at my client or something else!

I've read that you have to change ports in your web.config, which I've tried - same mish-mash.  Any clues???

I've just downloaded the latest Fiddler2 and put it onto my PC. I admit that I'm not a Fiddler guru, but I know enough to use it somewhat. I'm trying to determine what's going on with one of our websites, so I downloaded the latest Fiddler2, installed it and fired it up. Then I brought up my browser (IE11 on Windows 7 Ultimate, 64-bit). The website is protected with SSL, and so when I went to look at the header information Fiddler immediate told me that it was encrypted, but that it could decrypt it. I told it to do so, and then I started getting these popup messages from Fiddler2, over and over again. I don't know what to do about it, so help!

I'm seeing response text like this:

fiddler.network.https> Failed to secure existing connection for <url> . A call to SSPI failed, see inner exception. InnerException: System.ComponentModel.Win32Exception: The token supplied to the function is invalid

The server is Tomcat.

Fiddler v2.4.6.2

Thx,
