http_response returns output when not asked to do so?

http_response seems to return a request even when I do not ask for it. So when I use the code below to get a request, I get back a raw request and the formatted one. How do I stop the automatic request from coming back? I only want the one I request:

	http_response(key request_id, integer status, list metadata, string body)
	{
		integer x = llSubStringIndex(body, "<answer>") + 8;
		integer y = llSubStringIndex(body, "</answer>") - 1;
		string answer = llGetSubString(body, x, y);
		if(answer == "")
		{
		llWhisper(0,"Please try again later.");
		}
		else
		{
		llSay(0, answer);
		}
	}

On my wbpage, it returns <answer>My text to return to the LSL script</answer>
The http_response gives me this:

Object: er>My text to return to the LSL script

Then gives me this:
Object: My text to return to the LSL script
Which is how it SHOULD be.
If I comment out llSay(0,answer); it still puts out

Object: er>My text to return to the LSL script

which does not make sense if I am not telling the script to write that.

Hey, I just tried your code, copy and pasted.

Works exactly as you wanted.

My php script simply does:

<?
echo '<answer>My text to return to the LSL script</answer>';
?>

And I got just the text in <answer></answer>

Very strange. Let me look over my website script then. Perhaps it is outputting it again somwhere. Thanks for checking it for me. Much appreciated!!
