Queuing traffic in iRules - advisability!!

Thanks for the update and the link.

So how does an 'after' within a 'while' loop get treated? Does each execution of the 'after' result in connection suspension? Or because the 'after' is being executed within the context of a blocking command (while), does it in itself become blocking?

Will the following code block solidly for up to 120s? Or will it suspend 600 times?

set i 1
while {[table lookup "mytable"] ne "" } {
    if {$i > 600} {
         Ensure a single request can never keep queuing beyond 600 iterations
        break
    }
    after 200
    incr i
}
