Hi John,

 

As usual great article. One thing that makes this solution a bit cumbersome is lack of search/filter in datagroup interface (or I am not aware of such functionality?).

 

If there are hundreds or thousands of entries in datagroup it's hard to find the right one (to modify/delete) or check if given entry is already there. Any tips how to solve this?

 

I wonder as well how fast update in datagroup is picked up by iRule. I suspect that datagroup is not somehow cached when TCP connection is created and when HTTP_REQUEST is fired (can be multiple in one TCP connection) actual up-to-date content of datagroup is searched - Am I right?
