I never touched the Apache 'inner files', but now I need to add a string (that isn't static) to the end of some JavaScript files when serving them via Apache. What should I do / learn to achieve this? Where can I check for a request for a file (myfile.js) and then add a string to the client before he downloads the file?
I'd really like to learn how things work and I don't really have a clue of where to start.
Thanks in advance.
