I have written a script that pops some values into a database table, then, on the basis of that, performs an SQL Query to extract values across a range of tables, then build them into a URL for posting onwards to another site. So far, so good.

The problem arises, however, when I use LWP to post the values onto the server.

The script (which I have not seen, though it is an asp script), returns an HTTP 411 Content-Length expected error.

I know that the values are properly encoded, as they work when posted experimentally from a browser.

I suppose that what I'm really asking (having looked into setting values in the HTTP::Header section), is how to determine a Content-Length value, so that LWP does not report an error saying that "Content-Length set when there is not content, fixed at /usr/lib/perl5/vendor_perl/5.8.0/LWP/Protocol/http.pm line 194'.

Apart from the results returned from the server, there isn't much else that I can add.

Any help greatly appreciated.
