Using OllyDBG to find a string in a small ".exe" software and change it before sending the HTTP request.

I have a small ".exe" file, I need to change the HTTP request below before it sends out:

"GET /[login to view URL] HTTP/1.1

Content-Type: text/html

Host: [login to view URL]

Accept: text/html, */*

User-Agent: Mozilla/3.0 (compatible; Indy Library)"

I use OllyDBG to check the code of this ".exe". file, my goal is changing that IP address string "[login to view URL]" to " to "[login to view URL]"

It seems the code in this ".exe" software lead me into an infinite cycle when I trying to use F8(Step over.) to check the code step by step. I have found that HTTP request in "Registers Window" (ESI 00168020) before sending the HTTP request, but I don't know when it is being stored. I have attempted to set a "memory breakpoint" on that memory address "00168020", but I can't find that address in the "Memory Dump Window" before the infinite cycle.

You may need the software below to test this ".exe" file:

Windows XP virtual machine (test this ".exe" file)

Linux virtual machine(set the IP address to "[login to view URL]" to receive the HTTP request.)

OllyDBG(install it in the Windows XP virtual machine) - I can provide this

Smsniff(install it in the Windows XP virtual machine) - I can provide this

PEiD(install it in the Windows XP virtual machine) - I can provide this

You may need to download the whole software(3.7G) if the problem is too hard to solve.
I will show you the URL.

Hello, it's not mandatory to use OllyDBG for your project, it's possible to just use API hooking in order to solve your problem.
