client is caching connections.. i want to close that connection.. possible?

Hi,

 

 

I have this issue w/ a websphere client that when it tries to do a name lookup, it creates a connection and keeps that connection cached. It connects to a backend server using a normal virtual server, but then stays sticky onto that server because the connection never closes on the client or server side.

 

 

client a connects to server 1

 

client b connects to server 2

 

client c connects to server 3

 

there are no more clients and servers 1, 2, and 3 stay in use, while there is a farm of 20+ server and 17 are doing nothing.

 

 

I want to break the normal functionality of the f5 in reusing backend connections.

 

 

here's a sniff of the line..

 

summary:

 

giop request

 

giop request

 

[ack]

 

[ack]

 

giop request

 

giop request

 

[ack]

 

[ack]

 

repeat....

in frames 1 and 4, i have the GIOP request that i want to seach for and it is always going to recieve another GIOP request and then two [ACK]'s and then i would like to have the connection close and if it needs to create a new session, go through the three way hand shake and re-establish the connection.

 

 

first off, is this the right forum to discuss this, and number 2, can i achieve this w/ an irule.

 

 

secondly, is there a way for me to count packets and say, after the three way handshake happens, can you count 5 packets and then close the connection unconditionally?

 

 

thanks!
