Logging every request to a certain file

Question

I want to log all request- (and maybe also response-) headers of requests, that are made to a certain file on an Apache server. I have tried a php script, but that only fires when I request it directly. Is there any way to log all the requests on a file that I can specify? (If it does matter: in my case the file I want to log the requests for, is a mp4 file.)

Answer 1

Yes you can set and environmental variable to use for determining logging behavior

SetEnvIf Request_URI /this/is/a/url.html$ thisurllog
CustomLog thisurl.log common env=thisurllog
CustomLog access.log common env=!thisurllog

The last line will prevent the entries for that URI from logging in common access log. You can omit if you are OK with double logging into both logs.
