New to fiddler. I am trying to do a REST API curl request but getting a red 502 response.

Here is the curl request:

curl -X GET https://sandbox.forte.net/api/v3/organizations/org_333251/locations/loc_191620/customers/
-H "Content-Type: application/json"
-H "X-Forte-Auth-Organization-Id: org_333251" 
-H "Authorization: Basic Mjk3NjMwMGJiNjlmMDhiMmRmZTU3NzU0ZDkyMWI4Y2Q6NmU4N2QwZjUwMmE4ZGE5M"
-H "Accept: application/json"
-H "Cache-Control: no-cache"

It is a sandbox account so no problem if you want to play around with it.

All the credentials are good, and it works in Postman, but for the life of me I can't get it to work in Fiddler :(

What am I missing?

Dear Guys,
For some weeks now, I often have severe memory problems with Fiddler. Fiddler takes all memory, then all other applications need to access the pagefile and quickly the system becomes unusable. This happens every two days or once a week or so. It happens today and it happened two days ago.
* I don't stream any audio or video.
*  "Keep only" is set to 100.
* To me, it seems this is somehow correlated to Windows downloading some update packages. Not sure, though. 
Fiddler Version:

I have searched other forum discussions on this matter, and nothing works!

Every time I start fiddler I receive the error 19:49:11:2323 Fiddler.Network.AutoProxy> AutoProxy Detection failed.

I have deleted and reinstalled the certs several times and nothing works. 

I want to dig into HCPSS requests, but can't because of this error.

Hi!

I'm playing around autoresponder and its features.

Have tried to use *header action but it does not seem to work.

Rule itself is quite clear: METHOD:GET - to be sure I've not messed at this point I also tried it with action *drop and eveything seems to work("no connection" error message was shown in Chrome)

Actions were tried:

1. *header:Content-Type=application/octet-stream -- existing header, dash-style naming

2. *header:ContentType=application/octet-stream -- existing header, camelCase naming

3. *header:X-OWN=test -- new header, dash-style naming

4. *header:XOWN=test -- new header, camelCase naming

And then I've looked intoChrome's Developer Tools and there was no such headers shown.

Or is *header action applied to request(while I checked response)?

Have somebody used *header action successfully?

Thank you.

Hi!

There is something seems to be a bug.

For rule that contains additional check(e.g. METHOD:) alongside with URL match clicking "Test..." shows error message "Sorry, the TEST command can only be used with Rules that evaluate the URL.

Maybe it's because it's possible to edit matching pattern right in the "Test" popup(so it would need aditionally to parse rule string, take URL matching separately from other flags, allow it to be edited and finally to join all that again).

But currently it requires additional efforts to check such kind of rules:

1. Cut all the flags except REGEX:/EXCEPT:/<partial URL matching string>

2. Test it, modify if needed

3. Return all the flags back

4. Save the rule

Hi

I need to capture https traffic. I can do it using UI but i need to enable, configure and start fiddler from command line to capture https trafic  (Windows)

Is it possible to enable https capturing using only cmd in Windows?

I can start the fiddler from cmd in quit mode.

I can update keys in the register.

I can generate ssl certificate using makecert.exe.

I have no idea how to set the certificate to fiddler.

How can I force fiddler to generate ssl certificate automatically?

Where fiddler stores its private and public certificate?

P.s. I'll be appreciate if anyone can help me.

There are many issues of in my mac, but most painful is this copy ad paste issue. I need to create a document with the list of API responses and request but when I select text and try to copy and paste in notepad, it's not pasting.

Please if anyone can help me!

Hey,

I am conducting some tests on a web app using fiddler. An important test is sending in many of the same request at once. 

I am currently using shift+r on a request and sending in 10-50 at once, however fiddler will only send in 10 at once and then sequentially send in the other 40. 

Is there a way to send in all 50 at once, or is this just a limit of my network/server. 

Regards, 

Ben

Hi,

We are trying to use FiddlerCore API with C# for developing automation scripts with Selenium. Everything works perfectly in one of our client machine, whereas when we use the same script in another new machine with little changes (2 GB RAM and Dual core) everything is messed up.

When we start the script, we are calling starting Fiddler by

FiddlerCoreStartupFlags oFCSF = FiddlerCoreStartupFlags.Default;
int iPort = 8877;
Fiddler.FiddlerApplication.Startup(iPort, oFCSF);

Fiddler is started up and holding our application from loading completely. Our AUT needs to mentioned in Exceptions of proxy settings: "Do not use proxy for the addresses beginning with". Since this is getting cleared up after we start Fiddler, our AUT is getting stopped from loading completely and we cannot continue with our testing. Can you please help on this.

Thanks,
