I suppose you have to know if it is a GET or POST CGI web service, the URL, fi encrypted https, the variable names, the input and possible output mime types, so you can construct a correct URL and HTTP POST input section and are ready for the response message. JAVASCRIPT to get a text resource from a URL should be in tutorials all over.

When I execute the below server side perl program I am getting HTTP status 411: Length Required Error.

Code:
#!/usr/bin/perl
use lib '/usr/lib/perl5/5.8.8/SOAP-Lite-0.65_3/lib';
use SOAP::Transport::HTTP;
use Demo;
  SOAP::Transport::HTTP::CGI
    -> dispatch_to('Demo')
    -> handle;

Do i need to make any change in the above program?Any help would be appreciated.

Thanks,

This service demands a "Content-Length: #" in the http header you send after the GET/POST. The creator of the post-header payload should measure it ahead of time and generate this header line. That is in the fine; in the gross, it seems this is common running the script on the command line not on the server:
