htaccess condition for redirect pld page to new page.

Hello,

I am just changing one of my webpage with slight difference in its url. I was just wondering how can i redirect my old page (if someone got indexed page )

to the new page.

my old url page address would be like this

Quote:

mysite.com/categories/blogname

(e.g-bloganame would like anything myworld.wordpress.com etc)

so it ll become like this-

Quote:

mysite.com/categories/myworld.wordpress.com

and now on the new webpage my address would be like the following where i want to append the username who's blog is registered on my site.

(earler it was anonymous blog so he/she need to claim it first(he/she ll get username using this process) and then eventually it ll become his/her own blog)

So my new address will be like

Quote:

mysite.com/categories/myworld.wordpress.com-info4bein/

where info4bein is the username.

I have found this

I am trying to understanding this and i wanted to do something similar.

This is my mod-write definition for the category page which are having their username

Quote:

RewriteRule categories/([-a-z|A-Z|0-9|-|_|.|&]+)$ /categories/$1/ [R=301,L]

RewriteRule categories/([-a-z|A-Z|0-9|-|_|.|&]+)/$ /myfolder/categories\.php?url=$1

Can anyone please check this and guide me in the right direction.

Thanks in advance.

Any help???
