Altostratus
Altostratus4.x to 9.x irule conversion
I'm a newbie with tcl and am having difficulty getting them over from 4.x to 9.4. It seems to balk at an "[undefined procedure sS] [sS]" in the regex statements. It does this at each one of the bracket expressions. What does this mean and how do I resolve it? Thanks in advance for your help.
when HTTP_REQUEST {
if { [http_uri] contains "^/[sS][cC](/.{0,}|$)" } {
use pool CSHTTP
}
elseif { [http_uri] contains "^/PlanSharedResourcesClient/.*" } {
use pool PlanResourcesPool
}
elseif { [http_uri] contains "^/PlanCentral/.*" } {
use pool PlanResourcesPool
}
elseif { [http_uri] contains ".*(\.htm|\.htc|\.js|\.gif|\.png|\.jpg|\.css)" } {
use pool PlanResourcesPool
}
elseif { [http_uri] contains "^/[nN][mM][fF](/.{0,}|$)" } {
use pool DOCPool
}
elseif { [http_uri] contains "^/[wW]eb[sS]ervices(/.{0,}|$)" } {
use pool WebServices
}
elseif { [http_uri] contains "^/[fF][sS](/.{0,}|$)" } {
use pool Feedback
}
else {
use pool NaviNetHTTP
}
}

Hi,
if you have more and more checking to do it may become more efficient to use the command switch instead.
other tips:
- Contains takes more CPU than starts_with and ends_with.
- Regular expression is taking a lot of cpu
So, in some of your statement you can remove the regular expression you specified by using those commands.
Those update will make it definitely faster
