Write Rewrite Rule For /page/25?cat=8 to /?cat=8/page/25
Write Rewrite Rule For /page/25?tag=cool to /?tag=cool/page/25
It needs to accept and redirect:
/page/24?cat=8/page/2 to /?cat=8/page/24
/page/23?cat=8/page/2 to /?cat=8/page/23
/page/22?cat=7/page/2 to /?cat=7/page/22
/page/21?cat=7/page/2 to /?cat=7/page/21
Basically all pages need to be redirected to their correct counterpart e.g numbers are replaceable ?cat=x and /page/x?
This should be a simple job, please make a good offer. If you have multiple years of experience with mod_rewrite rules you are preferred.
