I'm sorry mathieu - you'll have to elaborate on what you mean by "post a web response to a page."

Are you familiar with asp.net (I just realized you posted this question in the C# section)?

I have a webpage called receive.aspx that is being called and a response of a web service needs to be passed.
U could say it is like a listener.

The question is if I am calling a page i need to somehow pass the respone through the page.

The value of the formdata should contain the web response. I need to see if the the response is hitting the page. How Shoud I setup my ui.

I'm starting to follow you matheiu. You're either saying:
A) that you need send a response back to the client that originally made a POST to your recieve.aspx
or
B)that you need to send data to a DIFFERENT web page or service as part work that recieve.aspx is doing.

if your question is A) above, then the answer is simple - Just use Response as you already are to display RETURN_CODE and RETURN_ERROR_TEXT. The response doesn't have to be HTML. It can be anything - XML for example or even binary data (Response.BinaryWrite).

If your question is B) you'll have to make an HTTP request directly from your code with the HttpWebRequest class. This is a good example:
