NimbostratusHi there, I am beginner in terms of coding irules. I seek your help in coding an irule. My scenario is I need to switch multiple uris. I kind of know how to do it usinga switch statement. But as part of standards followd at my work place. I need to code something generic which can be used across different platforms. So I need help how to use a class file to trigger uri swictc. Thanks for the help.

CirrostratusFrom a data-group, you don't need to use a switch statement. Below is something I use:
ltm data-group internal url-redirect-class {
records {
/from1 {
data /to1
}
/from2 {
data /to2
}
}
}
ltm rule redirect-rule {
when HTTP_REQUEST {
set path [string tolower [HTTP::path]]
set redirect_url [class match -value -- $path equals url-redirect-class]
if { $redirect_url ne "" } {
HTTP::redirect $redirect_url
return
}
}
}

CirrusCirrusIf you are looking to switch (or route) traffic to different pools based on the URI you can use an irule simliar to this:
when HTTP_REQUEST {
set uri [string tolower [HTTP::uri]]
switch -glob $uri {
/uri1* {
pool http_pool1
}
/uri2* {
pool http_pool2
}
/uri3* -
/uri4* -
/uri5* {
pool http_pool3
} default {
pool http_pool4
}
}
}
