ACE Layer 7 Load Balancing.

Hello

I am trying to configure ACE to load balance base on the user URL. If it matches the specific URL, the traffic will be sent to server farm 1 else the traffic will be sent to server farm 2. Below is my configuration. Please let me know if this will work.

Thanks,

Server Farm Config:

serverfarm host SF_L7_SFAAdmin

description L7 load balancing for SFA Admin

predictor leastconns slowstart 5400

rserver RS_VC_PROD_2

inservice

serverfarm host SF_SFA

Your config concept is correct, howvever your url match is wrong, don't include the host portion in the url the match statement would be:

match http url SFAAdmin/*

this implies that you will have a / and at leat one character after / following

SFAAdmin

if there might be nothing after SFAAdmin you want to do:

match http url SFAAdmin.*

if you want to loadbalance on host portion you would use a match on the host header not url.

Hello,

Please correct me if I am wrong.

http://sfaweb/sfaadmin/report/home.aspx, http://sfaweb/sfaadmin/default.aspx or http://sfaweb/sfaadmin/sales/invoice.aspx can be accomplishing by using match http url sfadmin/* command.

Thanks,

if you use regex you should perhaps try this one to match.

http://sfaweb/sfaadmin?(.*)

http://...sfadmin(Something else or not)

If you are not familiar with regex you could do your tests with: http://www.weitz.de/regex-coach/

It would be:

match http url /sfaadmin/.*
