Nimbostratusirule performance: combine multiple irules
Hi,
We have an several irules that we are trying simplify and combine for better performance.
first to block certain URI's
when HTTP_REQUEST {
switch [HTTP::uri] {
"/proxy/" -
"/content/xmlmovies/undefined" -
"/duas/" {
HTTP::respond 404 content "404 - file not found."}
}
To log request with certain content size
if { [HTTP::header Content-Length] >= 9000 } {
log local0. "[HTTP::header Content-Length] byte [HTTP::method] request from [IP::client_addr] for [HTTP::host][HTTP::uri]"
}
Redirect to certain URI's to HTTPs
switch -glob [string tolower [HTTP::path]] {
"/login*" {
if {[TCP::local_port] == 80} {
HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
}
"/app/login_user*" {
if {[TCP::local_port] == 80} {
HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
}
"/app/new*" {
if {[TCP::local_port] == 80} {
HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
}
"/app/associate_new*" {
if {[TCP::local_port] == 80} {
HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
}
"/account*" {
if {[TCP::local_port] == 80} {
HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}
}
}
}

JP_42120I found something from another post...
The original if {..} used "startswith"...
I guess for the below switch {...} to work a * is used in the string...
when HTTP_REQUEST {
set path [string tolower [HTTP::path]]
switch $path {
"/proxy/*" -
"/content/xmlmovies/undefined*" -
"/duas/*" {
HTTP::respond 404 content "404 - file not found."
Does this look okay?- What_Lies_Bene1

Almost, I just think you need to use switch -glob $path { as you are using a wildcard character. - JP_42120gotcha!
so somthing like this?
when HTTP_REQUEST {
switch -glob [string tolower [HTTP::path]] {
"/proxy/*" -
"/content/xmlmovies/undefined*" -
"/duas/*" {
HTTP::respond 404 content "404 - file not found."
thanks. - What_Lies_Bene1Looks good. You're welcome.
