Calling commands by string / reflection

Hi Stephan,

I can confirm you're correct for 11.4.1 at least. I haven't built my iRule exactly but fiddled did a lot of testing. I can turn attributes like

HTTP::uri

into variables just by set

x "HTTP::uri"

. then I can get the command HTTP::uri by

$x

. Alternatively if I do

[$x]

it returns the value of the HTTP uri.

I even did something like

when HTTP_REQUEST {
    set a HTTP::header
    set b "replace"
    set c "host"
    set d "new.host.header.value"
    $a $b $c $d
}

And the last line actually replaced the host header.

I haven't been able to turn things like "starts_with" into variables though - every approach has resulted in a run time error but I think I've gotten around it by using

matches_glob

for all string matching and leaving it up to the user to enter the correct wildcards into the datagroup that feeds into the iRule.

I think this is pretty much solved but I'll build my iRule when I get a chance again and repost in a couple of days with an update.

I'm quite sure this is going to cut my iRule down to a third of its size at least. Thanks for your help again!
