AltostratusHi Guys, I have created an iRule to select a pool based on the URL the user goes to.
testurl.com goes to pool_group1
testurl.com/diagnostics/* goes to pool_group2
The testurl.com/diagnostics/* works fine, however the testurl.com doesn't seem to work at all when the iRule is applied to the Virtual Server. Is there something I'm missing?
Cirrusit could be because you are searching on http::path, but im not 100% about this. But i have made a suggestion, that takes a slightly different approach:
when HTTP_REQUEST {
if { [string tolower [HTTP::uri]] starts_with "diagnostics"} {
pool pool_group2
persist source_adr 255.255.255.255 1800
}
else { pool pool_group1
}
}
MVPHai Kai, 😉
[HTTP::uri][HTTP::path][string tolower]Cheers, Kai
Cirrusyeah..was a bit unsure about that...so i just used http::uri out of old habit, and probably a lack of coffee:D
string tolower should almost be mandatory, if you ask me..has saved me countless hours of troubleshooting, because of end users using capital letters when typing in the url..
AltostratusSomething seems to be wrong with the syntax?
Please see error below
/CCRegressionTEST/irule_CCdiagnosticsimages_redirect:4: error: ["invalid argument source_adr; expected syntax spec: (add|carp|cookie|delete|dest_addr|hash|lookup|msrdp|none|simple|sip|source_addr|ssl|sticky|uie|universal) "][persist source_adr 255.255.255.255 1800 ]
MVPHi phipse,
you iRule looks absolutely valid^^
For testing purposes you may try to the iRules below and then take a look to your logfiles...
Test1: Forwarding every request to pool_group1
when HTTP_REQUEST {
log local0.debug "iRule executed..."
pool pool_group1
}
Test2: Same as your iRule with added logging
when HTTP_REQUEST {
log local0.debug "Debug: iRule executed..."
switch -glob -- [HTTP::uri] {
"/diagnostics/*" {
log local0.debug "Debug: Hit the /diagnostics path."
persist source_addr 255.255.255.255 1800
pool pool_group2
}
default {
log local0.debug "Debug: Hit the default path"
pool pool_group1
}
}
}
Cheers, Kai
Nimbostratusadd the following to the irule to see what are we getting back from the server
when HTTP_RESPONSE {
log local0.debug "server Status respose [HTTP::status] if you get 301 or 302 is a redirect, 4XX are authentication and page not found, 200 good respose from the server"
log local0.debug "Http::header [HTTP::header names ] "
log local0.debug "header location [HTTP::header Location]"
}
