ACE redirect to different URI on rserver

Richard Bradfield — Wed, 16 May 2012 08:57:29 GMT

We use JDE and up to now part of the tools was Apache which would redirect as follows

http://alias.server to http://real.server:13333/main.maf

the latest version no longer uses Apache so I was wondering how I can do it on the ACE

of course there is no problem going from alias.server port 80 to real.server:13333 but how can I add the URI main.maf?

Good morning,

If what you are trying to do is just rewriting the request so that the "/main.maf" sting is added to the URL, then, I'm afraid the answer is that it's not possible.

What you could do is first doing a redirect (not rewrite) from "http://vip_ip/" to "http://vip_ip:13333/main.maf" and then be load-balanced to the servers (for which the request would be "http://server_ip:13333/main.maf")

For more details on how to configure the redirection, you can refer to the link below

http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/vA2_3_0/configuration/slb/guide/rsfarms.html#wp1013201

If you need more details on how to achieve this configuration, please, let me know.

Regards

Daniel

Daniel,

Ok Just need some help in getting it right

This is what I have at the moment

rserver host CHIJTW55

description CHIJTW55

ip address 172.16.98.106

inservice

serverfarm host JDEDV

description JDEDV servers

failaction purge

probe tcp13333

rserver CHIJTW55 13333

inservice

class-map match-any JDEDV_vip

2 match virtual-address 172.16.73.10 tcp eq www

so do I add the following to change the VIP?

rserver redirect JDEDV_RED

webhost-redirection http://172.16.73.10:13333/main.maf 301

what else do I need?

Hi,

You first need to associate the redirect rserver with the JDEDV_vip. Then create a new VIP for the same IP address but port 13333 and associate the JDEDV serverfarm to it.

Daniel,

been looking at this further. I am using the ACE in one arm mode, so there is only one interface.

I can't see how it works, i can create a policy map for the redirect server and the original VIP, but does that get applied to the vlan interface, if so how does the second part work, when I use another Vip with the real server that would also need to be applied to the interface...this is where I am getting lost.

The configuration would look like the following:

rserver host CHIJTW55

description CHIJTW55

ip address 172.16.98.106

inservice

rserver redirect JDEDV_RED

webhost-redirection http://172.16.73.10:13333/main.maf 301

serverfarm host JDEDV

description JDEDV servers

failaction purge

probe tcp13333

rserver CHIJTW55 13333

inservice

serverfarm redirect REDIRECT_FARM

rserver JDEDV_RED

inservice

class-map match-any JDEDV_vip_80

2 match virtual-address 172.16.73.10 tcp eq www

class-map match-any JDEDV_vip_13333

2 match virtual-address 172.16.73.10 tcp eq 13333

policy-map type loadbalance first-match JDEDV_80

class class-default

serverfarm REDIRECT_FARM

policy-map type loadbalance first-match JDEDV_13333

class class-default

serverfarm JDEDV

policy-map multi-match MULTI_POLICY

class JDEDV_vip_80

loadbalance vip inservice

loadbalance policy JDEDV_80

class JDEDV_vip_13333

loadbalance vip inservice

loadbalance policy JDEDV_13333

interface vlan X

service-policy input MULTI_POLICY

I hope this helps

I had just about worked it out a couple of hours ago, the only thing left is

when I go to http://JDEDV the URL is displayed as

http://172.16.73.10:13333/main.maf instead of http://JDEDV/main.maf

The redirection is currently pointing to the IP address of the VIP. If you want the browser to display the DNS name, you should use that in the redirect statement.
