Problems posting form info to a .asp site using LWP

[sublow]

I have attempted to automate posting info to a form on a remote website but keep getting a response (mostly in german) saying "your system can probably not handle *.asp files".

A similar program using LWP with the GET method works fine for a separate website but I seem to remember reading somewhere that LWP doesnt work with .asp sites. Is this true? If so, is there a way around the problem as I have hundreds of proteins to scan and cutting and pasting this info into my browser takes far too long!

Any ideas would be gratefully received.

Check :

• If you get a 30x HTTP Response from the server, for LWP doesn't handle POST as the IIS server expect when there's a redirection (look at Redirect_ok)...
  
• Fake the UserAgent to an usual one 'Mozilla..'
• Fake a referer (setting it to the page where the form is...)


In last resort use SocketWorkbench to find what's different with a posting via your browser...

If you are having problems, it should not be due the technology deployed on the server side.

LWP is a set of Web client libraries that make requests using HTTP and other protocols. ASP is a server-side technology that is used to send responses to HTTP requests. So, as long as LWP and ASP deal with HTTP well (which in my experience they do - I dislike ASP, but there are other reasons for that), the specific languages and technologies deployed should not cause a problem.
