Jim-
That is actually very easy to do on ACE. You just need to know what the initial URL is and the URL that you would like to redirect to.
First, you need to add 2 classes which match the URL that your client initially request + the domain:
class-map type http loadbalance match-any Domain1
3 match http header Host header-value "www\.cisco\.com"
class-map type http loadbalance match-any Domain1-URL
3 match http header Host header-value "www\.cisco\.com"
4 match http url "/login.html"
class-map type http loadbalance match-any Domain2
2 match http header Host header-value "mail\.cisco\.com"
class-map type http loadbalance match-any Domain2-URL
2 match http header Host header-value "mail\.cisco\.com"
3 match http url "/login.html"
Then you need to create the redirect rserver and serverfarm:
rserver redirect Domain1Redirect
webhost-redirection /newloginpage/index.html
inservice
rserver redirect Domain1Redirect
webhost-redirection /newloginpage/index.html
inservice
serverfarm redirect Domain1RedirectFarm
rserver Domain1Redirect
inservice
serverfarm redirect Domain2RedirectFarm
rserver Domain1Redirect
inservice
Then you need to update the loadbalance policy map to include the 2 new classes. Be sure to add them in the order below:
policy-map type loadbalance http first-match LBPM
class Domain1-URL
serverfarm Domain1Redirect
class Domain1
serverfarm Domain1Servers
class Domain2-URL
serverfarm Domain2Redirect
class Domain2
serverfarm Domain2Servers
With this configuration, whenever a user accesses mail.cisco.com/login.html, they will be redirected to mail.cisco.com/newloginpage/index.html
There are actually some really cool things you can do with redirects in general. Say your client accesses mail.cisco.com/stuff/index.html or mail.cisco.com/login/pictures.html. You need to match any pages the client accesses in the /stuff/ folder and redirect the client to the mail.cisco.com/newlogin/stuff/X where x is the same page/object the client initially accessed.. You class map would match http url "/stuff/.*"
And instead of:
rserver redirect Domain1Redirect
webhost-redirection /newloginpage/stuff/index.html
inservice
Use this:
rserver redirect Domain1Redirect
webhost-redirection /newloginpage/%p
inservice
%p copies the entire url and pastes it in after the expression you enter. %h copies the host header that the client sent as well. %h is useful where you need to send the client to a new protocol. I.e. you match http, but want to send the client to https.
i.e.:
rserver redirect Domain1Redirect
webhost-redirection https://%h/newloginpage/%p
inservice
