[users@httpd] The logic behind URL rewriting

[Sanjay Saha <sanjaydotsaha@xxxxxxxxxxx>]

Hi List,

If anybody could tell here,
the logic behind an _expression_ matching .
I needed to tweak an apache _expression_ matching to suit my 
subdomain's url rewriting . 

 <VirtualHost *>
 ServerName aaa.domain.com
 RedirectMatch (.*)\ .*$ https://www.domain.com/aaa$1
       ------x-------
This match is confirming any url like below,

=> bbb.domain.com
=> https://www.bbb.domain.com/index.jsp
=> www.bbb.domain.com
=>domain.com/bbb

rediected to as following ,

=>https://www.domain.com/bbb/index.jsp
=>https://www.domain.com/bbb/


Now i cann't figure out whats the function of $1 in the Redirectmatch here 

Regards...
