Re: Can I serve CLI Applications using Apache (Apache Users)

I have already bumped into CGI (after asking the question here).

However, I have some issues with CGI. For example, I have to add HEADERS maintaining CRLF etc in the output. However, I want the CLI app to be totally independent. I mean, I want to output regular text or json without any header. So, what I really want is:

CLI_APP | ADD_UI | ADD_CGI_HEADER

Where CLI_APP gives me pure json. ADD_UI adds HTML, CSS, JS on the json output. And ADD_CGI_HEADER adds the extra stuff that is needed to make the final response sendable via the server.

Please note that when the user will send a request, it will have to go through the total pipeline. Also please note that, I can always call ADD_UI at the end of CLI_APP and call ADD_CGI_HEADER at the end of ADD_UI. But that way, I am not decoupling. And the later binaries will be dependent on the previous ones. This is not something I want. I want to pipe the outputs to get the final response.

How can I do that? Do I need to extend the apache server in any way (like creating any module or something like that).

Thanks and Best Regards,
Ahmad Ismail

you can use CGI to prototype it, and FastCGI later for performance (if
