What type of iRule would help?

First off, sorry this is going to be really long, but no other way to explain...called support and they suggested I come here to help with building the right iRule.

 

 

We have Big-IP infront of an application (Livelink) with 4 virtual web instances (x.x.45.3, x.x.45.4, x.x.45.5, x.x.45.6 all port 80). We access with VIP (assume livelink.com). Initial redirection works fine...and lets assume it redirects to x.x.45.3.

 

 

Now when application gets this call, the application itself will redirect based upon users ip address. If ip address is in the local area, it then sends the redirect address of livelink.com/livelink/livelink.exe.

 

 

The Load Balancer then gets this address and cannot interpret it. So I wrote an iRule to strip off the /livleink/livelink.exe but this didn't work as well. I think I need to create an iRule to send it to the right resource and not sure how to do.

 

 

There is a lot more involved, but trying to get this issue solved to begin with. Any help would be greatly appreciated.

 

 

I've also attached an explanation I wrote directly to the Livelink support to see if my interpretation of how the traffic works below. Haven't had any confirmation as of yet, but I think this is right.

    I'm curious why it is you think the BIG-IP is having a problem handling the full "livelink.com/livelink/livelink.exe" URL. This shouldn't be a problem at all, assuming the hostname hasn't changed, and still points to the virtual server in question on the BIG-IP.

     

     

    If it does, then the request should be passed properly, even without an iRule, and the path shouldn't matter at all.

     

     

    What behavior are you seeing when you say "The Load Balancer then gets this address and cannot interpret it."?

    Your reply actually got me to thinking that perhaps the way the consultant configured our virtual web sites may be wrong...and am looking into that instead of the Load Balancers. They were pointing me at the Load Balancers because they felt it couldn't handle the pathing...but if you say that should be no problem I'll look into that instead.

     

     

    If I can't come up with anything I'll contact support as from you say, we probably shouldn't require an iRule.

     

     

    Might be back here if this all doesn't work, but thanks for your quick response.
