With C# I want to replace text in a site with fiddler. I looked through all the sources but couldn't find anything.

Example: "Not changed try again." At http://metin2bot.net/fiddler/test.php I want to change the text to "Changed successfully".

So when I enter the site, I want it to receive the response I have determined.

Is it possible to do this with C#?

Please help. I love you fiddler. Thx

Hey,

So currently I am coding a Program and want to use the CertMaker.dll as embedded resource and want to load it from resources so I don't have to extract it to the same folder as the program i am running. This also works, it creates the certificate as it should but it doesn't fake the requests then.

I cant use the CertMaker.dll as Resource. Is there any workaround?

Hello


I'm using fiddler to test thick client application network request with IBOSS proxy , but seems fiddler is not able to intercept requests as IBOSS is continuously changing proxy with its background service.  Fiddler is showing The system proxy was changed, Click to reenable capturing.  

My System proxy is point to .pac file of IBOSS. 
Fiddler gateway tab is set to Use System Proxy.

I've tried several options like  changing gateway option to use IBOSS .pac file and all, but none of them worked.

any help would be appreciated.

Thanks

hi guys, i very tks all to make this software

 

i have a problem, but i dont know how to do, because i'm not a dev  :(

but when i config proxy (IP and Port show in picture) in my fone, i just can access to my VPS address, can not access the internet, just show Connection not Private

tks very much, sorry for my English, i'm not good  :( 

hi, 

I'm trying to understand how to solve a problem i'm having, I hope someone with more experience can enlighten me. 

I'm developing a small app wich does some api call via WinHttp.WinHttpRequest.5.1 . I'm having trouble with a particular get request: the result i get shows some strange characters instead of accented characters. However when I use Fidler to do the seme get request (headers and everyhing are exactly identical) the result i get is correct. the response  I get on Fidler has the characters in the correct way in raw, in text view and all the other tabs except for hex view!
in the hex view tab of the response, the text that i can see in the right column is exactly showing in the same wrong way as I see it in my program.

I would like to understand how the text shown in the right column of the hex vie tab of the response is treated/transformed by Fidler so as to become the correct text shown in the other tabs. If  i could understand that, I think I could apply the same tranformation on the wrong text that I get in my app.

thanks for the help
