Hello this seems like a pretty simply question but I can't locate any info.

 

When you start a fiddler capture it looks like the net traffic is all captured into ram. I have a very random issue that occurs once every few days... I need to leave fiddler running but after a day or two it consumes all free ram and starts to destabilize the server.

 

Is there anyway to write capture info to file instead of ram? 

 

Thanks.

 

I had a custom button to clear the log following the instructions in this post: http://www.telerik.com/forums/remove-all-as-a-single-click-button-on-the-toolbar

The button doesn't show up anymore. I think this functionality broke from the latest update. 
Please let me know how to get this functionality back.

Hi,

Probably not the right place to ask, but ??

how do i mark my post / issue as solved ??

There is no tick box and I can't edit the title of the post?

Hi,

 

This must have been asked before !! ( so sorry about that )

 

I'm making calls to a remote server which has a web service (soap based) on port 7047.

I'm using soap ui to trace the call, but unless it goes via port 80 it does not get captured.

Is there a way to tell fiddler to listen not to 80 but some other port 

Thnaks

I installed Mono 4.2.4 (newer version of Mono didn't work at all) and installed Fiddler in a folder I have write access to.  I followed the instructions for syncing Fiddler and am able to successfully start Fiddler.  However, each time I click the File --> Capture link, I get the following pop-up:

osascript wants to make changes.

Touch ID or enter your password to allow this.

 

I enter my password, and it is accepted, but still no traffic is captured.  When I click the capture link again, I get the same pop-up.

Is there any way to block partial URLs in Fiddler? I know that you can block an entire URL, but say the end of this specific URL contains the time in it, it will be a different URL every single time generate that request.

 

 

I currently am blocking URLs by going into my autoresponder and pasting A URL in the following way:

"if request matches..." (example)

"then respond with..." (*reset) 

 

My idea would be to create the same autoresponder but instead of "if request matches...", having "if request contains..." or something along that lines, is this possible?

I'm currently using  Burp Suite with fiddler to get around the PAC file issues with Burp. It was working fine yesterday. Now every time I try to use fiddler it deletes my PAC file setting. Also the 'Show Current Gateway Info' doesn't work anymore either. While Fiddler is open and I select 'Click to reenable capturing' it will just delete my PAC file setting again and I can't use it. I haven't made any changes since I was using it yesterday. Any ideas?

I have an application that I use for work all the time that makes a web request to a server and responds with a unique key that I need for certain purposes. I don't like having to launch the application whenever I want a key, so I am using proxifier to forward the traffic to fiddler. I've tried it on two machines with out success. One machine uses windows 7 without .net 4 so I'm using fiddler2. On that machine the error is

 

. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

 

The other machine uses fiddler 4 and the error is

fiddler.network.https> HTTPS handshake to 104.28.15.252 (for #1) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

Win32 (SChannel) Native Error Code: 0x80090326

In both cases the request it fails on is the same
