Hello, I added fast cgi handler in perl. Perl scripts were working even when i haven't added anything for cgi. However they were running seperate processes for each request. I configured the external app like this: Name lsperld Address uds://tmp/lshttpd/lsperl.sock Notes Not Set Max Connections 20 Environment FCGI_PERL_MAX_REQ=500 Initial Request Timeout (secs) 120 Retry Timeout (secs) 0 Persistent Connection Yes Connection Keepalive Timeout Not Set Response Buffering No Auto Start Yes Command $SERVER_ROOT/fcgi-bin/lsperld.fpl Back Log 100 Instances 20 Run On Start Up Not Set Max Idle Time Not Set Priority Not Set Memory Soft Limit (bytes) 100M Memory Hard Limit (bytes) 120M Process Soft Limit 1000 Process Hard Limit 1100 Next I added a script handler for pl files. Restarted the server and ran the script. The script still ran in a seperate process. I then removed this line from the top of my perl script "#!/usr/bin/perl" and it gave me this error: "lscgid: execve(): Exec format error" The server can run .cgi extension files too even though i haven't added cgi extensions as a script handler ? are they added in by default ? How can i run the perl scripts as fast cgi process ? I have installed the fastcgi module in perl.
