It's the HTML decode code, I never put that many spaces in the querystring. Back to the drawling board.

Oops!!

Actually its another stack overflow problem but in the dynamic file generator this time. Thank you for your help. I have everything logged so... more work to do. My wife's real happy about that.

Anyone up for a quick test? AJAX, Web Camera, and Spinneret LED.

Mike,

I just retried POST on a WinXP machine (Opera), but with nil results. I put a sniffer on the connection, so I could see exactly what was being sent. Here it is:

POST /login.shp HTTP/1.1

Firefox works fine. Here's what it sent:

It looks like the Content-Type and Content-Length lines are swapped between the two. I suspect you might be counting characters right after Content-Length instead of after the blank line. Right?

Thanks Phil that helps. I thought it was a Linux/Windows issue, looks like it's browser related. I was able to reproduce the issue.

@Phil It's kinda' weird. Opera causes an error when sending a post. So, the header request is never processed. It looks like the request is empty, 0 bytes but the page eventually renders. It must have something to so with my HttpRequest object or timeout logic.

To find the body, I'm looking for a \n\n or \r\n\r\n

I just checked, and both Opera and Firefox send \r\n at the end of each HTTP line.
