iRule for RTSP

In regards to using the information in the persistence table...you'll need to use the persist lookup command, like your rule alludes to. It looks like you need a little further clarification on the options of this command.

In a great post unruley made a while back (which you can find by searching for persist lookup in the forums) here Click here

He outlines the usage of the persist command. I believe the part you're interested in is the second part of the information that follows:

The following instances of the persist command select persist:

NOTE: items marked with are meant to be replaced with some sort of value or evaluated expression. Arguments bracketed by [] are used to note they are optional and should not be confused with Tcl command evaluation.

persist simple [] []        
persist source_addr [] []        
persist sticky [] []        
persist dest_addr [] []        
persist ssl []        
persist msrdp []        
persist cookie [insert [] [] |        
                rewrite [] [] |        
                passive [] |        
                hash  [{  [] } []] ]        
persist uie  []        
persist hash  []        

The following instances of the persist command can be used to manipulate the persistence table directly:

persist add   []        
persist lookup   [all|node|port|pool]  
  "all" or no specification returns a list containing        
  the node, port and pool name.  Specifying any of the other        
  return types will return the specified item only.        
              
persist delete          
    = simple | source_addr | sticky | dest_addr | ssl | uie | hash        
    =  |        
         {  [any virtual|service|pool] [pool ] }        
  the latter key specification is used to create/access        
  persist entries across virtuals, services, or pools.        

Hopefully this helps to clear things up. I'll also work on getting this info into the Wiki for future reference.
