NimbostratusMixing HTTP_REQUEST && HTTP_REQUEST_DATA
Hi All,
Looking for some help on this irule.I currently have the following irule:
when HTTP_REQUEST {
set redirectPort [ getfield [HTTP::host] ":" 2]
log local0. "port: $redirectPort"
if { $redirectPort equals "8003" } {
pool MMF_pool_8003
} elseif { $redirectPort equals "8004" } {
pool MMF_pool_8004
} else {
pool MMF_pool
}
}
The logical thinking in the above is:
Check HTTP Headers to get Host Port .According to this Host Port then the traffic is separated into different pools.
But i wish to put in an extra "else if" in the middle, that checks Http Data, checks first couple of bites and then assign a pool according to this.
Is this possible?
Regards,
William
William_Murphy1Hi all,
An update on this. Have tried the following to see if it works:
when HTTP_REQUEST {
set redirectPort [ getfield [HTTP::host] ":" 2]
binary scan [HTTP::payload] HexPayLoad
if { $redirectPort equals "8003" } {
pool MMF_pool_8003
log local0. "GET:3"
} elseif { $redirectPort equals "8004" }{
pool MMF_pool_8004
log local0. "GET:4"
} elseif { $HexPayLoad starts_with "8C80" } {
pool MMF_pool
log local0. "Post"
} else {
pool MMF_pool_8002
}
}
Irules editor accepts but getting errors in F5 logs.
Having trouble reading HexPayLoad.

Any help would be appreciated.
