CirrusWell, do you really want to limit the LTM to 8k for the headers? Default http profile in LTM accepts 32k so you don't have to worry about that(LTM is superior to ACE, we are almost done replacing all of our ACEs). For the "sticky http-cookie..." you will want to use a cookie persistence profile with the default session cookie option to match the config. Here's a little more info on cookie persistence, https://support.f5.com/kb/en-us/solutions/public/6000/900/sol6917.html.
yogesh_gaikwad_Hi Brad, Thanks for your reply I am transferring the services as is to avoid any problems, I am not sure if the customer had requested such kind of config on the ACE, I will try not to limit the LTM to 8k for the headers, but if in case it does not work as expected, then what should be the procedure to achieve similar config on F5 as the above one BR, Yogesh- Brad_ParkerWith how the ACE is working I don't anticipate you having to change this as ACE just allows it through after reading 8k, its non-blocking. However, on LTM if you choose to change the "Maximum Header Size" any request with a header larger than that will have its connection reset.
- yogesh_gaikwad_So there is no option on the F5 to continue the load balancing even if the header size increases of a specific request?
- Brad_ParkerYou need to set your value higher than valid requests would be. However, I think most web servers only accept 16k and smaller by default. So, The default F5 value should be sufficient on most circumstances.
