Hello,
I am new to using Fiddler Web Debugger.  How do I measure performance of a website with the application?  Can you provide the basics? 

I see this in the right hand side when a page is loaded up.  In there anymore to performance tools that Fiddler Web Debugger has?

Requests started at:  36:56.8
Responses completed at:  36:58.2
Sequence (clock) duration:  00:01.4
Aggregate Session duration: 00:01.5
 TCP/IP Connect duration: 10ms
 

Rule Config

regex:(?insx)\/0Pl5sssO4/.+\.js$ #Versafe.js
C:\Users\chernyakov\Desktop\versafe\static.js

I would expect Autoresponder to respond with file contents. Instead, it rewrites my request 



GET http://xx.xx.43.176C:\Users\chernyakov\Desktop\script\static.js/ HTTP/1.1
Host: Xx.xx.43.176C:\Users\chernyakov\Desktop\script\static.js
Proxy-Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
Accept: */*

Rule: regex:(?insx)\/0Pl5sssO4/.+\.js$ #script.js
and selected a file on a file system in the second combo-box 

I would expect that the AutoResponder would respond with the file contents, instead, it rewrites URLs to 

GET http://XX.XX.43.176C:\Users\chernyakov\Desktop\script\static.js/ HTTP/1.1
Host: XX.XX.43.176C:\Users\chernyakov\Desktop\script\static.js

All other headers are seem to be fine 

Is that a bug, or I am configuring it wrong ? 

I want use Fiddler Script and I have those packets with this host name :

wl.search.ar.ns.test.com

If I use oSession.HostnameIs how can I do ?

So ? 

if (oSession.HostnameIs("wl.search.ar.ns.test.com")) {
            oSession.hostname="199.156.34.12";
}

is it correct ?

Mostly I use Fiddler for creating Visual Studio web tests, by exporting to a ".webtest" file. As I record a set of steps I add comments about what is shown on the screen and what actions are being performed. Unfortunately the ".webtest" file omits many of the comments. While recording I just want to add a comment to the most recent session, I do not want to spend time choosing a session that should be written to the file.

How can I persuade Fiddler to write all of my comments to the ".webtest" file? I have looked at the code of some plugins and also (via "ilspy") at VSWebTestExport.dll but there is no obvious way of writing out the comments without making changes to file "FiddlerWebTest.cs".

I'm trying to use fiddler to debug an Exchange ActiveSync error. Unfortunately, starting Outlook with fiddler triggers an error message:
"There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site outlook.office365.com".

I suppose this is some rudimentary certificate-pinning from Outlook. How could I solve this? Would editing the name of the certificate in certmgr.msc do the job?

Thanks in advance

I’m trying to run FiddlerCap Web Recorder.  When I check ‘Decrypt HTTPS traffic’ as True, I get a dialog box appear titled ‘A note about HTTPS Decryption”, upon selecting okay, the 'Decrypt HTTPS traffic'  appears as false again and a note in the bottom left footer of the application states ‘Sorry, unable
to create root certificate’. 

I'd appreciate any help in resolving this.

Thanks.   

Hi,

I'm having some issues adding fiddler.exe as a reference in VS2013, no matter what i do VS does not recognize it as a reference when building the solution.
Intellisense reads it just fine and i can add it and any object within in it to the code without any issues.
I've tried this both in a new project and an in an existing inspector solution I've grabbed from github (I'm modifying the WCF binary inspector to decode FastInfoset encoded messages), also tried copying the exe locally instead of grabbing it from the Program Files directory.
Has anyone experienced this issue or has any insights in how to solve it?

P.S.
For fiddler 4 is it possible to use .NET 4/4.5 project profiles for fiddler (4) plugins? the fiddler documentation is quite outdated  and it still instructs me to create a .NET 3.5 solution.

Thanks.

How do I set the filter for multiple URLs? For example, I want to do something like this:

Show only if URL contains: .php OR .aspx

I looked at the Filters documentation, but it didn't say much about the URL filter.

Hi,

Does somebody have a sample rule to capture a sessionId from a response and use it as an input in the subsequent request?

Sorry, if this issue is already answered before. I am very new to fiddler.

Sample could be for any standard application on the web. Like login/logout to twitter or yelp etc.

Thanks much in advance.

Regards,
S
