mod rewrite with & without page number

[poe]

i am trying to do a rewrite on 2 different types of urls..

 

the first configuration can be 1 of 3 ways...

 

http://localhost/site/index.php?type=top&pg=2
http://localhost/site/index.php?type=new&pg=3
http://localhost/site/index.php?type=fav&pg=1 etc...

 

i want to rewrite so it shows as

 

http://localhost/site/top/2/
http://localhost/site/new/3/
http://localhost/site/fav/

 

notice how the third sample (pg 1) doesnt need to show fav/1/ in the url, but instead show as /fav/

 

 

so far i have :

 

RewriteEngine On

RewriteRule ^top/([a-zA-Z0-9]+)[/]?(.*)$ index.php?type=top&pg=$1
RewriteRule ^new/([a-zA-Z0-9]+)[/]?(.*)$ index.php?type=new&pg=$1
RewriteRule ^fav/([a-zA-Z0-9]+)[/]?(.*)$ index.php?type=fav&pg=$1

 

... but i am missing how i can leave off the last part of the url if it is page 1

 

 

 

the second configuration is similar to the first except it is done by an infinite number of categories, which i would like to avoid listing each rule out seperatley per category.

 

the url will look like this...

 

http://localhost/site/index.php?cat=apparel&pg=2
http://localhost/site/index.php?cat=toys&pg=1
http://localhost/site/index.php?cat=footwear&pg=6
etc.... (can have unlimited number of categories)

 

 

and again my goal is to have the url look like :

 

http://localhost/site/apparel/2/
http://localhost/site/toys/
http://localhost/site/footwear/6/

 

and just like the first configuration, if on page 1, i wish to leave the pg out of the url.

 

so far i am trying to work with something like this :

 

RewriteRule ^([a-zA-Z0-9]+)/([a-zA-Z0-9]+)[/]?(.*)$ index.php?cat=$1&pg=$2

 

it fails when i try a url with no page defined (page 1)

 

thanks
