intercept and change a css file in reverse proxy

[Evuraan <evuraan@xxxxxxxxx>]

I've a reverse proxy, and I've to fix somebody else's mess(!)

I am looking to intercept and change a specific css file's content from:

    src: url("/online/wrong.eot");

to:

    src: url("/online/correct.eot");

Is this possible? Any pointers will be much appreciated!

Thanks!
