[iRule] to trim hex value and send it to pool

Thanks Kevin,

I noticed you use binary, that's probably because yours is HTTP. In my case, my server expects hex, so here's mine:

Code

when CLIENTSSL_HANDSHAKE {
SSL::collect
}

when CLIENTSSL_DATA {
     collect hex values
    binary scan [SSL::payload] H200 hex
    log local0. $hex
    set original [SSL::payload]
     look at the 8th and 9th hex value
    log local0. [string range $hex 8 9]
    if {[string index $hex 8] equals "2" and [string index $hex 9] equals "9" }{
         log local0. "Test UAT" 
         SSL::payload replace 0 7 ""
         SSL::payload replace 0 0 $original 
         pool Value29_To_UAT_Svr1
       }

Is it possible for me to set SSL::payload to it's original after pool redirection? I use

Code

set original [SSL::payload]

However

Code

SSL::payload replace 0 0 $original 

didn't work.

Here's what I think:

For example, original SSL payload total length is 40 bytes. I replace first 7 bytes with empty space, that means now it has 33 bytes. Even with SSL::payload replace 0 0 $original, it still has 33 bytes.

Is there anyway at some point I use back the original SSL payload? It's a pain, because some of the server requires the first 7, some older one does not.
