Redirect from page=2&showtopic=2

[Aleksandr Sozykin]

Some search engines resort url parameters.

url 1: /index.php?showtopic=2&page=2

to new url 2: /index.php?page=2&showtopic=2

"url 1" redirected to /2-topic/2-page

but "new url 2" not redirected to /2-topic/2-page

problem: clones of pages

How to solve this in ipb 3.4.5? Or may be some modifications in files...

For example:

http://community.invisionpower.com/index.php?page=2&showtopic=375533

redirected to

http://community.invisionpower.com/page=2

P.S. Please moderators move the topic in the right section of the forum.
