It seems the ACE is not capable of handling the response on port 80 and the redirection from 80 to 443 even if the url requested is different.

Connections to host-dummy2 shouldn't be redirected and should be served on port 80.

Hi,

you will never reach the class CLASS-REDIRECT because you will have a match on web2. They both match on 10.1.1.1:80.

What are you exactly trying to accomplish?

If I'm correct:

Traffic to 10.1.1.1:443 will be balanced over serverfarm webfarm and decrypted if the HOST header-value contains dummy-host.example.com. What should be done if the VIP matches but the header doesn't?

Traffic to 10.1.1.1:80 will be balanced over serverfarm webfarm if the HOST header-value contains dummy-host2.example.com. What should be done if the VIP matches but the header doesn't?

Traffic to 10.1.1.1:80 will be redirected to 10.1.1.1:443.

Is this correct?

Hello

>>you will never reach the class CLASS-REDIRECT because you will have a match on web2. They both match on 10.1.1.1:80.

There should be a match on "web2" only if Host header-value contains dummy-host2.example.com else traffic will reach CLASS-REDIRECT.

So if you target http://dummy-host.example.com, you will be redirected to https://dummy-host.example.com. Working.

If you target https://dummy-host.example.com, then you will reach the right serverfarm. Same as the one above. Working.

If you target http://dummy-host2.example.com, you should reach the serverfarm and NOT be redirected to https://dummy-host2.example.com... which is happening right now. Not working

Hi,

If you want that to happen, I would do it like this:

create a single policy-map for 10.1.1.1:80 and:

- when your URL contains dummy-host2.example.com, loadbalance over the serverfarm, ELSE, redirect it.

policy-map type loadbalance http first-match webl7policy2

class L7web2

serverfarm webfarm

class class-default

serverfarm farm-https

The class-default catches everything the more specific class maps in before it don't match.

HTH,

Dario

Thx Dario. It worked fine :)
