Hello,

The main problem is that v2 does not support map files, so there's no way to convert it except writing separate rules for each line in mapfile (which may be quite a lot).
So, please tell how many entries you have in your mapfiles and I'll tell you if having them all in separate rules won't hinder the performance.

Return to ISAPI_Rewrite 2.x
