Getting URL parameters with mod_rewrite

Here is my 开发者_如何学运维current rewrite rule

RewriteRule ^page/([^/\.]+)/?$ index.php?page=$1 [L]
RewriteRule ^post/([^/\.]+)/?$ index.php?post=$1 [L]
RewriteRule ^cat/([^/\.]+)/?$ index.php?cat=$1 [L]

three lines to do basically the same thing. Is there a way I can clean this up a bit? Is there one line that will accomplish this?

Also, Is there a way to pull multiple variables from a single url string? So if I had something like:

http://www.mysite.com?page=foo&id=123&color=red

how would I convert it to this:

http://www.mysite.com/page/foo/id/123/color/red

RewriteRule ^(cat|post|page)/([^/\.]+)/?$ index.php?$1=$2 [L]

because jacek_K to you one part, I give you answer of second part : to rewrite this URL(http://www.mysite.com/page/foo/id/123/color/red), use this:

RewriteRule ^page\/([^/\.]+)\/id\/(\d+)\/color\/([^/\.]+)   index.php?page=$1&id=$2&color=$3 [L]
