Re: [squid-users] Storeurl program,what's wrong with it ?

Hey 金 戈,

Squid storeurl_rewrite feature was introduced in squid version 2.6-7
which is not supported anymore.

I am working on another version which called StoreID which replaces
storeurl_rewrite.
It will be integrated into squid 3.3 which is now on Beta.
To find out what is your error you should understand better what you are
aiming for.

If you are willing to try the new feature it will be available soon.

Just a Note on your small program:
The regex you are using is not optimized and you should use less ".*"
and use a more strict approach on letters and characters.

Regards,
Eliezer
