NimbostratusManipulate TCP header
Due to the existing bug, the RST from client always causes trouble to server. Then I would like to block RST in BIGIP. However, I cannot find any iRule commands of manipluating TCP header. Any workaround ?
Thanks in advance !

There aren't any existing functions to get or change TCP flags. Here are a couple of related posts:

Aaron- hoolioBy the way, I suppose in theory you could do this manually by collecting the TCP packet and using binary scan to get/change the data by offsets. Paul posted a good example of using binary scan to drop specific packets (Click here)

xiangyang_zhangMany thanks for information. It seems Paul post is talking about processing TCP load too.
