Any iRules in use? Access Policy?

 

Ran into a similar issue, everything was normal, client - server connect went fine but still recieved a 404. Ended up being misplacement of a splash page iRule. It was placed ahead of the information gathering and resulted in error.

Hi Nicolas - thanks for the response.

 

Yes - we did have the irules in place for the pool selection.

 

The issues here was the SSL persistence on VS. I have that removed and the issues set to fixed.

 

Now the SSL persistence is enabled via irule as recommended by F5.
