Configure Regular Expression on Cisco ACE

[cannone78]

Hi all,

I need to configure a load balance based on url filtering:

All the traffic sent to https://home/can should be load balanced on a group of server (eg. x1, x2, x3); while all the traffic sent to https://home/can/<any-sub-directory> should be load balanced on other server (ex. X4 X5).

My question is: how can I configure correct url regular expression to correctly filter  the two above url?

I'm thinking something like this but I'm not sure if I on the right way:

• "https://home/can" or https://home/can\n ------> for the 1st
• https://home/can/.*         -------->                      for the 2nd

Many thanks in advance for your support

You can create two Class maps type https and specify something like the bellow 

(config)# class-map type https inspect HTTP_INSPECT

(config-cmap-http-insp)# match header Host header-value 

.*home/can

For the second one make it like 

 match header Host header-value 

.*home/can.*

Many thanks for your answer very clear.

Only the last doubt: since the directory 'can' of my path could change, If I need to make two generic filter without specify the exact name:

1. https://home/ --> to server x1,x2,x3
2. https://home//sub-directory   ---> to server x4,x5

For the 1st filter, can I configure somethink to filter a generic directory excluding subdirectory?

Something like https://home/*/

Many thanks for you support.
