I have a set of ruby cgi scripts, that works when trying in localhost.
When a user connects from internet, the server gets the following errors:

    [20/Feb/2005 15:56:04 +0000]  [error 411] Length Required

Why is happening such thing to remote users? and why not to local users?
All my html code is generated with CGI objects, so the code have always 
the following statements for example:

Content-Type: text/html
Content-Length: 170

I've readed that 411 error means that the Content-Lenght is not being 
sent or something.

What can i do?
Thanks
