Hi Team,

Hi,

My name is Nicholas and I am the Product Manager at Acunetix.

Every so often, we come across Acunetix users who are also using Fiddler to test their web applications. So we have implemented support for Fiddler Session Archives (Fiddler exports), which can be used to pre-seed a scan. This is very useful as it gives a head start to the Acunetix Vulnerability Scanner when crawling the web application, and the user might have already logged HTTP requests in Fiddler to parts of the web applications that are not linked to from the main URL.

More information about how to do this can be found at http://www.acunetix.com/blog/docs/how-to-pre-seed-a-crawl-using-a-fiddler-session-archive-saz-file/

I hope you find this Acunetix update useful.

I have a sporadic problem on an HTTPS site that requires a client CAC cert.  Problem started a few months ago.  At any given time, IE will prompt the user (windows security) to select their cert and press OK to continue on.

Problem is - is just keeps re-prompting for the cert - an endless loop when they press ok. It just keeps them prompting to select the cert again over and over.  They have to kill the browser in task manager and restart IE.  I CANNOT automatically re-create this problem on the fly.  It sporadically happens.  Maybe on the first attempt,   May happen in 5 minutes or may take 2 hours, or maybe not for the whole day as the user works in the site.  When this problem has happened to me, i have opened control panel -> Internet options -> and have cleared the SSL state, but it ignores when I select the cert and press ok.  It just keeps prompting me to select a cert.

I am trying to figure out if the the SSL state cache is not being cached, getting dumped, corrupted, network issues, etc. - OR if their is something wrong with the Windows security choose certificate GUI box (Wininet) that is causing the problem.

I have dumped the regular cert that i use for the authentication in the fiddler directory (ClientCertificate.cer), but would like fiddler to allow the windows security GUI to allow me to choose which cert i use (like it does when fiddler isn't running).  Any clues or way i can make fiddler use the windows select cert box (like normal)?

   Thanks,

      Jason

I've been running into some unexpected and strangely consistent HTTP/1.1 504 Fiddler - Receive Failure, and when looking into the response I see a the X-ServerSocket value to be two values: 

X-SERVERSOCKET: REUSE ServerPipe#1321REUSE ServerPipe#384*NEW*

This would seem to imply that the two server sockets were used for the connection, this seems bizarre. Are there conditions where this should happen?

Hi folks,

 I am pretty much new to fiddler. I heard that I can capture custom requests from fiddler so that I can use them in my performance testing tool Load Runner. Is there any settings required in order to generate custom requests?

ex: let's say I am hitting at "http://www.google.com" , so for this, the request which I am getting should be in Custom Request form. something like this..

web_custom_request("allocate", 
"URL=https://www.google.com", 
"Method=POST", 
"TargetFrame=", 
"Resource=0", 
"RecContentType=application/json", 
"Mode=HTML", 
"EncType=application/json; charset=utf-8", 
"Body=
Last);

Please do not hesitate to reach me if any thing is missing.

 

Thanks in advance,

Kantu

I am currently using the below script in custom rules to highlight the session green and put "found" into the custom column, if the word "hello" is found in the session.

What I am trying to workout now, is how can I adjust this to display a count of "hello" into the custom column?

 

Script:

if (oSession.utilFindInResponse("hello", false)>-1 && oSession.utilFindInResponse("startMap", false)>-1){
oSession["ui-color"] = "green"

oSession["ui-customcolumn"]="found"

 

Thanks

I am working in a ui project which had a dataservice in a public server. I need to redirect the service calls only to remote . like

http://localhost/project/service/user to http://192.168.3.250:8080/project/service/user

http://localhost/project/service/edit to http://192.168.3.250:8080/project/service/edit

I need to replace the part of the uri and get the response from the remote server.

I don't know if I am just Kryptonite for proxies, or what, but I cannot get Fiddler to work for my needs. I have an HP Stream 7 tablet running Win 8.1 phone. 

I need to get fiddler to capture traffic for a metro app I am testing, but the app is in perpetual load while running Fiddler. 
I can run IE 11 just fine and Fiddler is capturing IE traffic. 
I went into Win8 config on Fiddler and exempt everything from loopback as the fiddler set up said to do. 
Fiddler is set to decrypt HTTPS traffic and I installed the trust certificate.

Am I missing something? I would appreciate some help as soon as possible.

Thank you,
Lynn

Hello,

I am new to fiddler. I don't know yet how it works. I followed few online videos but those are not very helpful in my case.

I would like to edit a website javascript. I tried firebug but the js it not appearing to be editable in firebug.

I know that the website only uses client side validation by using javascript.

I would like to edit but but i dont know how i can edit it by using the fiddler.

Anyone can help me please?

 Currently I have Fiddler's Host Remapping feature configured like so:

127.0.0.1:10092     *WebsiteA.com
127.0.0.1:10092     *WebsiteA.de
127.0.0.1:10092     *WebsiteA.es
127.0.0.1:10092     *WebsiteA.co.uk
127.0.0.1:10092     *WebsiteA.fr
127.0.0.1:10092     *WebsiteA.it
 
127.0.0.1:10091     *m.WebsiteB.com
127.0.0.1:10091     *m.WebsiteB.com.au
127.0.0.1:10091     *m.WebsiteB.de
127.0.0.1:10091     *m.WebsiteB.es
127.0.0.1:10091     *m.WebsiteB.co.uk
127.0.0.1:10091     *m.WebsiteB.fr
127.0.0.1:10091     *m.WebsiteB.it
                       
127.0.0.1:10093     *WebsiteB.com
127.0.0.1:10093     *WebsiteB.com.au
127.0.0.1:10093     *WebsiteB.de
127.0.0.1:10093     *WebsiteB.es
127.0.0.1:10093     *WebsiteB.co.uk
127.0.0.1:10093     *WebsiteB.fr
127.0.0.1:10093     *WebsiteB.it

How can I use a wildcard for the Top Level Domain?

I tried to use the code below in the Fiddler Rules script's OnBeforeRequest() but am not having success. How can this be done?

if (oSession.host.Contains('.websiteB.')) {
   //oSession.host='127.0.0.1';
    oSession.m_hostIP= '127.0.0.1';
    oSession.port=10091;
   // MessageBox.Show(oSession);         
}
