How to get only exact query string send by user in apache log file?

  • 772

Apaches %r log format outputs: "GET /server?id=1 HTTP/2.0".

I need to have only the exact same query parameter value ?id=1 as separate field in my logs.

Thus i tried the %q option, which unfortunately outputs for the same request:

?ReturnUrl=Example.aspx?id=1

For sure there is a rewrite involved, but there must be a way to get exactly what the client send, right? How?

apache-2.4

    Okay, I got confused in my testing and overlooked that I already had the ?ReturnUrl=Example.aspx part in the address bar and appended to that ?id=1, which obviously resulted in the output shown above.

    But there are modifiers < and > which may be used to define if a logged expression is after redirects or before. Important is that:

    %s, %U, %T, %D, and %r look at the original request while all others look at the final request

    Thus you should better use %<q to be equal with %r.
