Hiding CGI-Perl Code...How?

Sometimes I notice servers screw up on calls to CGI-Perl programs and instead of them launching the perl script, they actually show you the perl code like a text file being viewed in the broweser.

I'd hate for this to happen to my CGI-Perl code and would love to take any measures to prevent this.  What options do i have?

I've heard of using FILTER:: to hide your source code, but I really don't know much else than the name.  I've also heard of converting the perl source code into byte-code or C and compiling.  

Please, any help you can give me on hiding the contents of my perl code would be GREATLY APPRECIATED!

Thanks.

There are two possible causes of this:
one would be a runaway ", or '  during a print.  This should be easy enough to track down if you actually test your program after writing it.

The other cause would be not setting up the cgi-bin directory as a cgi directory.  If this is not done, and depending on the extension, and how the server handles it, it could be displayed as text/html.

Once you have your scripts running ok, you only need to worry about the first one.  Most runaway quotes will be caught at comile time by Perl.  However it is possible for the quotes to be just wrong enough to print your statement and continue printing your code beyond that.  There is no way around this, other than running your script, and viewing it yourself.

The other possibility that occasionally happens is that the script isn't set executable.  ALWAYS be sure to run "chmod 755" on the script files.  I've had that happen on occasion...if it's not executable, the source will show in the browser.
