Attached is the patch (generated from diff -Naur).

The main changes are made in HttpHeaderTools.c, but the error I am
getting is:

helperHandleRead: unexpected read from header_rewriter #1, 161 bytes

...which is debug in the helper.c file.

Thanks!
James

Ok.

If you could post the patch it would be easier to help you out.

If not done already I would probably add a lookup cache as well to avoid

repeated helper lookups for the same user-agent string.
