I have the following problem. I have my script /usr/lib/cgi-bin/login.cgi
and two page in /var/www, home.html and welcome.html.
When I log in /var/www/home.html with email and password, then login.cgi to extract exact user informations from mysql. Now I'd like start welcome.html page from login.cgi and passing user informations trought parameters.
How can I solve this problem?

Hi -

a) it's easy,
... and ...
b) how you *send* the parameters depends on whether you're using "GET" or "POST"
... and ...
c) how you *read* the parameters depends entirely on what language you're using for your CGI script.

I'm using GET in home.html. When I log in home.html with email and password, then login.cgi extract users information. I'd like that login.cgi to start welcome.html and to pass this information to home.html. What method or functions I must use in cgi script?

I'm using perl for cgi script and html/css for web pages.

Cool - great!

Google for "Perl CGI tutorial" - you'll find lots of stuff.

Here's a nice, straightforward example - this actually might be everything you need:

http://en.wikipedia.org/wiki/CGI.pm

Here's another short (but still useful) link:

http://perl.about.com/od/cgiweb/a/perlcgiform.htm

CAVEAT:
"CGI" is by definition "server-side". If you have a website on the Internet, how *much* you can do is limited by what your ISP allows you to do....

PS:
By default, CGI.pm forms use "POST". You can use the "-method" option to explicitly specify "GET" or "POST".

What you are attempting to do is create a 'session'. The concept of sessions is not part of HTTP, and so 'cookies' were invented to support the notion of holding transient values between page loads, so that it becomes possible to do what you are trying to do. You can also pass information between pages by embedding such information in hidden fields in HTML pages. Your CGI will have to grab the values in the hidden fields, and regenerate it as necessary when it builds new pages that are sent to the browser. In Perl and PHP, there are modules available that assist in the creation of sessions using CGI. For Perl, on CPAN, search for 'CGI session'. I don't do PHP, but I have it on good authority that it is similarly straightforward to establish sessions.
