ScriptAliasMatch apache
 

ScriptAliasMatch ^/~([a-zA-Z0-9]+)/cgi-bin/(.+) /home/$1/cgi-bin/$2

will map a request to http://example.com/~user/cgi-bin/script.cgi to the path /home/user/cgi-bin/script.cgi and will treat the resulting file as a CGI script.

I want to access http://example.com/cgi-bin/script.cgi as my path is /home/user/www/cgi-bin/script.cgi what changes i have to make in ScriptAliasMatch condition.

Hi,

If you want to map the main apache cgi-bin directory to a specific user cgi-bin directory you don't need ScriptAliasMatch. ScriptAlias is enough
If you insist, you can use:
Regards

Thanks for the help.

I try both the option but it did not work .
I also try this one

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_URI} !~
RewriteCond %{REQUEST_URI} ^\/.*\.pl$
RewriteCond %{DOCUMENT_ROOT} \/home\/mst3k\/public_html
RewriteRule ^(.*)$ /~mst3k/$1 [L]

but it also didnt work

What exactly are you trying to do and how it's not working. Check apache logs to see what's happening
If you want a request for http://example.com/cgi-bin/script.cgi to be served from the cgi directory in /home/mst3k/public_html/cgi-bin, then you need the just ScriptAlias above modified like this (added the specific username)
