CGI.pm problem
Hello, When I try to make a CGI object in my Apache/mod_perl handler a la $q = CGI-new(); The server just don't reply. Actually it works just fine until I try to submit a form, then it just hangs and Apache doesn't send anything back. If I remove this object creation line, then I can submit my form (but then its no use, i can't use the data). What could be the problem? Rgds, Viljo

I seem to remember a problem with mod_perl and an older version of CGI.pm where CGI.pm was fooled into thinking it was run in command line mode. If you are seeing the following line in your logs then this is definately the cause of your problem: (offline mode: enter name=value pairs on standard input) To fix this put $CGI::NO_DEBUG=1 near the top of your program or upgrade CGI.pm. Cees ps you should be using Apache::(Request|Cookie) to get your GET/POST/COOKIE parameters, as it is more efficient. ---

CGI.pm 3.x is supposed to have the args processing and html generation separated.

Ah, so there is. I grep'd an older version which didn't since I'd never heard of it before. You use Apache::Request to get query parameters the same way you do with CGI.pm's param() method. perldoc Apache::Request. Did you could try just importing the CGI.pm HTML functions? Personally, I prefer Template Toolkit for HTML generation. There are other templating systems too. Search the archives for discussions on the subject. Or as Stas suggested, check out the version 3 beta. I've been using it on my personal web server for a few months with no problems, though I don't use any of the HTML generation features. --Jeff At 10:32 AM 8/30/00 +0400, Alexei V.

But if I try functional way instead (commented in example) I see that $args is empty! In single-process mode (httpd -X) both examples work right. Why?
