Q&A
> HTTP and FTP clients
Description: 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. Answer: Problems posting form info to a .asp site using LWP
contributed by arhuman 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... | Answer: Problems posting form info to a .asp site using LWP

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.
