I am trying to understand how the installed version of my Fiddler on my server has created a dependency where if Fiddler is not running/memory resident my .Net application will not pass traffic via http/https.

We really like the product however want to be sure we can control access to our business critical applications without relying on 3rd part apps.  can someone please help me to understand what setting/where this can be changed so IE works wit or without Fiddler running? I think it has to do with the Web Session Manipulation feature, i have tried to replicate the issue however have not been able to. server OS 2008r2.

Initially I thought this was a bug from the Jetty HttpClient Java library, after I filled out a bug report and things were checked into we found out that Fiddler proxy replies to the CONNECT with a response that contains Connection: close.

I tried to capture the same traffic in Charles and it's working with no issues. Here is the link to my Jetty bug report page.

https://github.com/eclipse/jetty.project/issues/973#issuecomment-250836144

 

Here is the link to the log file  http://dropcanvas.com/11ltw

 

Any idea why it's working fine in Charles but not in Fiddler?

Hi Eric,
        I'm using fiddler with selenium(firefox) and configured firefox using details provided at http://blogs.telerik.com/fiddler/posts/13-04-01/configuring-firefox-for-fiddler.

Log.OnLogString Event handler has 2 Messages

Hi,
I'm using fiddler to intercept the calls from my web browser to a local server from about two months and it is simply AMAZING so thank you for this great tool.

Now I would like to use it in a manner a bit more complex. I would like to intercept the calls (XML/SOAP) form my local webserver (WebLogic) to a remote one of which obviously I know the specific IP and port.

I have some problem to configure the proxy used by Weblogic, in fact it seems that the standard manner doesn't work. Maybe it is a my fault (I'm not an expert in this field) or maybe the weblogic domain, configured by my company, has some particular restriction that prevent me to use a proxy.

I guess if there is a manner to redirect to fiddler all the outgoing request to a specific address on a specific port ad using an OS configuration instead of a local server configuration. I mean, when windows detects an outgoing connection to a specific remote address and port it automatically redirect (transparently) it to another, in this case to fiddler.

Is there an easy way to obtain this behaviour?
Thanks in advance.

Best regards,

Hello folks.

I am using Fiddler to inspect third party service below:
I can see the following line at the end of the service Raw view:
[14025056,11490323,11741683,11894131,12598439,10738317,12857184,13225140,11803292,12733331]
If I go to the TextView tab of the Fiddler I can see the save value. This value represent hsbc word. Is there anyway to get word not the value with the fiddler? 
.

Anyone else have this issue whereby Fiddler repeatedly invokes the Delete Browsing History function, at every capture start or change of filters, or,......, to the tune of 70 or 80 times every time?

This obviously slows things down quite a bit, so I'd like to work out why this is happening and get it turned off,

Hi there all, 

I just begin to use Fiddler in order to escape from my company firewall using a proxy. 

 

Before I had user+pass in order to out to internet and was easy to use putty tunnel 

...but now my company have change the things

Now we use a Smart Card with PIN and when I open explorer I just go out with out user + pass access. 

 

So can anybody please explain me how can I find what type of protocol we use 

in order to make Fiddler Proxy and use other programms like putty ... please 

 

Thanks in advance 

Denis

I don't really think this is even for this forum or this site. But I really have no idea where to go on this so even if no one can answer it on here could you maybe point me to a site where I could figure this out?


I'm a developer. We program a front-end GUI using AIR and a back-end using java. The java service listens on port 1813 for our requests from the GUI and then sends those requests off to a gateway server which returns the data to display.


For some reason, it works just fine in one scenario, but in another it doesn't. Keep in mind this used to work and I have no idea what changed. If I run my application, it starts up our java service. We then start sending requests to http://localhost:1813 form the GUI to the java service. When the application runs and sends these requests, I'm getting 502 errors. If I run the application and use POSTMAN to send the exact same request, I get a correct response.


The request is  xml and I have set the headers to application/xml. The method for both is POST. The only difference I can really see in the headers in Fiddler is that in the Transport section the  one that works using POSTMAN has "Connection: Keep-Alive" and the failed one from within the application has "Proxy-Connection: Keep-Alive". But I don't know enough to know if that matters or what it means or why it would say that.


I have attached a failed and successful image to show the headers in fiddler.

Thanks for any help. 

My fiddler can't exit totally.  Everytime I close fiddler, it will stay at background process. The next time I start it, I get a prompt indicating another fiddler is running.  So I have to kill the previous precess ,  while all my configuration can't be saved.

After searching, I got this https://twitter.com/ericlaw/status/618892680420982784

but I don't have AVG .   Please help me out .

Hello,

i have a problem with Fiddler. I tried everything and spent hours to find a solution but i can't find one myself.

We have written a software to communicate with different webshops to upload articles, import orders and so on.

I usually use fiddler to fix a problem and check the request/response.

It works with every webshopsystem except shopware which is using a REST API.

Fiddler shows the HTTP GET Requests but no POST or PUT.

It's on the same system, same software, same functions. I have no idea why it's not capturing these Requests.

 

Example:

We download the categories with HTTP GET http://websiteurl.de/api/categories ( shows up in Fiddler )

To upload a new categorie we use the same URL and everything, we just send a simple JSON via HTTP POST http://websiteurl.de/api/categories ( not showing up in Fiddler )

Any ideas would be appreciated.

Thank you.

Simon
