Getting below error for the VIP

Okay, let's break this down, starting with the iRule:

when HTTP_REQUEST { 
    if { [string tolower [HTTP::host]] ends_with ".directory.kamlesh.com" } { 
        pool pool_uat_jboss7 
        HTTP::uri "/rest2ldap" 
    } 
}

What you're saying here, is if the HTTP host header ends with ".directory.kamlesh.com", send that request to the pool_uat_jboss7 pool, and change the URI to /rest2ldap.

So the request to

http://uat2-jboss7.digital-solutions.kamlesh.com:8080/rest2ldap/users/admin_f2400731 

will match the HTTP host header requirement, send to the pool, and change the URI from /rest2ldap/users/admin_f2400731 to simply /rest2ldap.

The request to

http://uat1-jboss7.digital-solutions.kamlesh.com:8080/rest2ldap/users/admin_f2400731 

will also match the HTTP host header requirement, send to the pool, and change the URI from /rest2ldap/users/f2400731 to simply /rest2ldap.

It's important to realize here that you've not provided any logic to tell the difference between uat1 and uat2. Are these running on separate uat1 and uat2 VIPs, or just one VIP for both? Further, you're replacing the incoming URI with a static /rest2ldap. Is that what you really want it to do? In any case, it would seem that a request to /rest2ldap on one of the backend servers is producing a 404 error.

Here VIP port is 443 and node port is 8080.Customer is accessing VIP port 443

 

i.e.curl on https://uat-api.directory.kamlesh.com/users/admin_f2400731 I got an error : {"code":404,"reason":"Not Found","message":"Resource '' not found"}. Here there is One VIP for both nodes.

 

Thanks to suggest .Just to know do i need to change Irule or the issue is related to application ? Regards Kamlesh y

 

I made the following test on server. If I do a curl on http://uat2-jboss7.digital-solutions.kamlesh.com:8080/rest2ldap/users/admin_f2400731 I got an answer from my application.

Your iRule will ALWAYS change that to be http://uat-jboss7.digital-solutions.kamlesh.com:8080/rest2ldap

That is why it works direct to the server but not when processed by the BigIP. Try this:

when HTTP_REQUEST {
  set orig_uri [HTTP::uri]
  if { [string tolower [HTTP::host]] ends_with ".directory.kamlesh.com" } { 
    pool pool_uat_jboss7 
    HTTP::uri /rest2ldap$orig_uri
  } 
}
