[mapserver-users] Internal Server Error / proxy.cgi
Hi,
I'm using MS4W with Windows 7.
When I call "http://localhost:8081/cgi-bin/proxy.cgi";, the response is:
/Internal Server Error
/
/The server encountered an internal error or misconfiguration and was
unable to complete your request./
/Please contact the server administrator, ad...@local.domain and inform
them of the time the error occurred, and anything you might have done
that may have caused the error./
/More information about this error may be available in the server error log.
/
The "error.log" file contains:

I've modified "proxy.cgi" file at "allowedHosts" by adding "localhost:8081".
I must modify the first row of "proxy.cgi" file?
Can this issue related to the Windows 7 OS?
Thanks

Re: [mapserver-users] Internal Server Error / proxy.cgi Fixed
I've installed Python 2.7 and I've changed the first row of
"Proxy.cgi" file with "#! C:/Python27/python.exe -u"
