Migrating WAS6 to WAS8.5

We are currently migrating from WAS 6.0 (IBM-WebSphere Application Server ND) to WAS 8.5.

 

We take this migration to remove the IHS server with WAS plugin to transfer this functionality to the BigIP.

 

We followed this procedure: http://www.f5.com/pdf/deployment-guides/ibm-websphere-8-dg.pdf.

 

 

However, when the BigIP used as proxy, the WAS application server return the application port in the URL instead of 80.

 

For example:

Is it missing something up?

    I didn't see anything in the guide that addresses this "reverse proxy issue", and I can't speak for the WAS8.5 configuration, but at the very least I believe you can integrate a stream iRule to replace values in the response payload. Take a look at the STREAM::expression wiki page for some great examples of how to do this.

    Hi,

     

     

    The IHS insert a couple of feild in the http header that the WAS understand. It tell the WAS that the service has been proxyed.

     

     

    When you do a tcpdump on the IHS you will find the Header $WSSP with the value "80" ( in your case).

     

     

    You need to create a HTTP profile and insert that feild in it.

     

     

    look like this in tmsh:

     

     

    list ltm profile http http_was

     

    ltm profile http http_was {

     

    .

     

    .

     

    .

     

    header-insert "\\$WSSP: 80"

     

    .

     

    .

     

    .

     

     

    }

     

     

     

    let me know if it solve your problem...
