My site serves up documents from tocmat that sometimes have &‘s in the file names.

So

nick&janes.doc

Here is the URL we access it with:

http://mysite.com/sub/nick%26janes.doc

For some reason our version of Apache + OpenSSL fails to re-write this correctly due to some bug. So the %26 becomes an & and then the request is all broken, because http://mysite.com/sub/nick&janes.doc

Upgrading OpenSSL will fix the problem, but this unfortunately isn’t an option for several months.

As a work-around, we are trying to create a rewrite rule that can turn any %26 into a special character sequence…. let’s say ___--___. Then on Tomcat, we can use a filter to fix the URLs and thus no more problem.

Anyone know how I can write such a rewrite rule?

    RewriteRule ^(.*)&(.*)$ $1__-__$2 [N]

    This turns foo%26bar to foo__-__bar

    At that point you can use a Tomcat filter to change any URL with __-__ back to %26
