https front end and http backend

Hi there....I am having a small issue....I have a web app that is https based....I have installed the cert on the CSS, and DNS for this app points to the VIP....the client is wanting to have an https front end, and then load balance in http to the backend servers....the issue I am running into is that this only works if I have an active port 80 rule on that same VIP....if I suspend the port 80 rule and only leave the port 443 rule active on that VIP, it doesn't work....please see appropriate config portions below....Thanks in advance!

ANy suggestions? I have been trying this for a couple of days now...it works fine if the backend sessions are also https, but the client has changed their requirement....

Re: https front end and http backend

Hi,

Well I find this a little confusing. First of all I see clear traffic on port 81 and not 80, and you have a content rule in port 81, so I guess that is what you mean.

Now, it is expected that this will not work if you suspend the clear text rule since that this is the proper configuration.

You need to have the rule in port 443 to match traffic coming from the client and the clear text rule (port 81) to match traffic already decrypted coming from the SSL module

Re: https front end and http backend

Thanks for the quick reply....there is another port 80 rule setup for that vip....I was using that to test with the app until I got the front end https rules working....

my port 80 rules just says listen to 10.19.55.10 on port 80 and load balance btwn the webervers on port 8x in the back end...

I am trying to do https front end and http backend....

no where in my SSL config have I configured port 80....but when I suspend that rule it all fails....

I am wondering if the backend server sessions are happening properly?

I don't fully get what you mean by "You need to have the rule in port 443 to match traffic coming from the client and the clear text rule (port 81) to match traffic already decrypted coming from the SSL module"

Haven'tI done that?

Thanks again!
