HTTP headers too long error message

Hello,

I'm trying to run a REST API call to add a node to multiple pools. There are about 30 - 40 pools I'm trying to add the node to. When I run my command to add the node to the pool list, I'm getting the following error message:

{"code":400,"message":"HTTP headers too long!","errorStack":[]}

If I shorten the amount of pools I'm trying to add the node to, it works without issue. From my research, I believe that the POST method itself has no limitations as to how much data you can send. It sounds like whatever web server on the receiving end is the thing that determines how big of a payload it will accept in a POST. Is there a way to override the default F5 limitation or specify in my POST some way to extend how much it can accept? I would really like to be able to add nodes to a large amount of pools in a single POST instead of having to break it up in to chunks.

Thank you!
