Binary (HEX) payload replace in HTTP

Hi Aaron,

Thanks for link to related issue, strange how i miss it before.

So the final working script will looks like following:

when HTTP_RESPONSE {

set v_1_0 "\x8d\x90"
set v_1_1 "\x8d\x91"
set v_1_2 "\x8d\x92"

log local0. "START response parsing"

if { [regexp {\x8d\x92} [HTTP::payload]] } {
 log local0. "Found 8d92 = v1.2:"
}
if { [regexp {\x8d\x91} [HTTP::payload]] } {
 log local0. "Found 8d91 = v1.1:"
}
if { [regexp {\x8d\x90} [HTTP::payload]] } {
 log local0. "Found 8d90 = v1.0:"
}

 regsub $v_1_2 [HTTP::payload] $v_1_0 replaced
 regsub $v_1_1 $replaced $v_1_0 replaced

 HTTP::payload replace 0 [HTTP::payload length] [binary format a* $replaced]
 log local0. "STOP response processing"
 HTTP::release
}

As mentioned in old issue the "binary format ca*" was not working in my SW version BIG-IP 9.4.8 Build 396.1 Hotfix HF3

but "binary format a*" working as required.

thanks and regards,

Denis
