redirect irule
Hi,
We are moving off A10s to F5s and we have an old a10 aflex rule which redirects certain traffic to a particular pool.
when HTTP_REQUEST {
if { [HTTP::uri] contains "<xyz>"} {
pool test-pool.domain.com-443
} else {
}
}
Could I get the syntax to get this working on the F5 please?
Thanks
Adrian
The syntax you have there should work without modification; A10's language is, how can I put it, eerily similar to iRules.
I would strongly advise you (and anyone else using HTTP::uri) to use [HTTP::uri -normalized], though, to avoid an attacker being able to evade your iRule logic by encoding, escaping or inserting path traversal characters: https://clouddocs.f5.com/api/irules/HTTP__uri.html
Hope below example can help you:
if you match "aol" traffic is sent to aol_pool otherwise is sent to the default pool associated to the VS.
when HTTP_REQUEST {
# case sensitive
if { [HTTP::uri] contains "aol" } {
pool aol_pool
}}
In below cases we can the default pool in the code.
when HTTP_REQUEST {
# case sensitive
if { [HTTP::uri] contains "aol" } {
pool aol_pool
} else {
pool all_pool
}# case insensitive
if { [string tolower [HTTP::uri]] contains "aol" } {
pool aol_pool
} else {
pool all_pool
}
