CSS 11501 Not Passing HTTPS or 443

When I go directly to the server address I can resolve both 80 and 443.

When I go via vip I get port 80 but can't connect to port 443.

Simple pass-thru config not terminating the Cert on the CSS or using the SCM.

HI,

During the session of the client, the transition is made to SSL port 443 when the client selects a link on the page that redirects to https. This causes a new content rule to be hit and the client may be load-balanced to another server. As the traffic is now encrypted https (SSL/TLS), the CSS is not able to check above layer 4 (the TCP port number) for cookies, URLs etc., because the requests are encrypted when the information passes the CSS. In order to prevent the occurrence of this issue, configure the redirecting HREF on each server to point back to https at the same servers public address, not the VIP address, as shown here:

https://servers_own_ip_address/path"> secure site If your servers are in a private address space, configure SSL content rules for each server with a HREF on each server that points to the SSL Content rules VIP.

Below is the configuration example for your reference:

!Generated on 10/10/2001 18:12:17

!Active version: ap0500015s

configure

!************************** SERVICE**************************

service s1

ip address 10.10.1.101

!*************************** OWNER***************************

protocol tcp

port 80

url "/*"

advanced-balance arrowpoint-cookie

!--- Specify a port in the content rule to use this option.

!--- Port 80 traffic is used here.

!--- All clients must enable cookies on their browser.

add service s1

content s2-ssl

vip address 10.10.1.99

protocol tcp

add service s2

!--- Use this HREF on server S1 where switching from http to https:

https://10.10.1.101/applicationpath1/"> secure site s1

!--- Use this HREF on server S2 where switching from http to https:

https://10.10.1.102/applicationpath2"> secure site s2

!--- In the example, the addresses for servers s1 and s2 must be

!--- reachable from the client. If this is not the case, you must add a

!--- content rule for each server with a unique publicly routable VIP

!--- address and one service for each SSL server, as shown here:

content s1-ssl

vip address 10.10.1.88

protocol tcp port 443

application ssl

add service s1

active

content s2-ssl

vip address 10.10.1.99

protocol tcp port 443

application ssl

add service s2

active

!--- Use this HREF on server s1 where the switch from http to https occurs:

https://10.10.1.88/applicationpath1/> secure site s1

!--- Use this HREF on server s2 where the switch from http to https occurs:

https://10.10.1.99/applicationpath2> secure site s2

Hope this will help you.

Here are the error messages we are getting from the websphere box:

[Wed Dec 03 12:23:47 2008] [info] [client 10.1.104.174] [963db0] SSL0230I: SSL Handshake Failed, An incorrectly formatted SSL message was received.

[Wed Dec 03 12:23:50 2008] [info] [client 205.189.14.52] [963db0] SSL0226I: SSL Handshake Failed, I/O error during handshake.

Also, we haven't seen this to be an issue in the past. Typically, we allow access via 443 the client types the https://vipaddress and everything works as expected.

The request is going to 1 of 3 JVM sessions running on the Websphere box.

you should capture a sniffer trace frontend and backend of the css to verify what is going on.

Your config looks alright.
