Intercepting web requests from an application and modifying response

[Sailor_EDA]

Thanks for your suggestion JMP-JECXZ.

Would you also happen to know if there any generic tools that would allow me to "automate" this so I don't have to intercept the call everytime and could just code my response whenever a request is done to that address?

Fiddler is fine, you can put 'breakpoint' on request to intercept them before response or even after, and then edit the content (return content or query)

You might want to edit your hosts file to redirect the traffic and then run the webserver part on your computer. If it's a simple webcheck with static requests there are many tiny webservers or networks tools available which can serve the requests.

If it's more complicated you might need to switch to some script language to process and serve the requests.

But if it's just a simple patch you already know the location to I would prefer patching over running a webserver. You might have redirected other addresses in your hosts file which would get served with unknown data and might behave differently.
