I have a cgi script that I know works (as far as the code is concerned), but which cannot be accessed through my website. My hosting provider simply states that I need to edit the .htaccess file, but I have no idea what options/handlers I need to set in order to make the contents of a directory execute like c++.
How is this done?
You can’t on this service provider. A quick search of the Bluehost Kb gave this: https://my.bluehost.com/cgi/help/48
However, there is nothing stopping you just trying just putting your exe in the cgi-bin dir and seeing if it runs, but this probably won’t work.
In this case, you’d need to relink any C++ against the local target server, and I doubt that Bluehost would facilitate this — just too much support hassle for the few $ / month that you pay.
