iRule Data Group with string and regex

As Steve said, classes don't support regex-style searches, but you can use the contains operator, which is functionally equivalent to "*something*". So while you may have to add more specific content type identifiers, the good news is that you can consolidate all of the oddly-cased variations of the same types by using a [string tolower ] match context.

Ok, so I am planning on doing something like this.

 

 

Irule Data Group (should {} contain the value?)

 

ltm data-group internal /Common/images {

 

records {

 

.CSS { } Example .CSS {.CSS}

 

.FLV { }

 

.GIF { }

 

.JPEG { }

 

.JPG { }

 

.PDF { }

 

.PNG { }

 

.SWF { }

 

.TXT { }

 

.bmp { }

 

.css { }

 

.flv { }

 

.gif { }

 

.ico { }

 

.jpeg { }

 

.jpg { }

 

.js { }

 

.m4v { }

 

.mp4 { }

 

.mpv { }

 

.ogv { }

 

.pdf { }

 

.png { }

 

.swf { }

 

.ttf { }

 

.txt { }

 

.webm { }

 

}

 

type string

 

}

 

 

when HTTP_REQUEST {

 

if {[class match -value -- [string tolower HTTP::uri] contains images] } {

 

pool Apache_Pool_80

 

if { ([HTTP::uri] contains "/*.gif*") || ([HTTP::uri] contains "/qas*") } {

 

pool Weblogic_Pool

 

if {[HTTP::uri] contains "/webservices*" } {

 

pool Weblogic_Services_Pool

 

if {[HTTP::uri] contains "/atgws" } {

 

pool buybuybaby.com_services_80

 

} else {

 

pool Apache_Pool_80

 

}

 

}

 

}

 

}

 

}

 

 

Something like that should work. Else you could use a switch statement to check the file types in the iRule itself.

when HTTP_REQUEST {
switch -glob [string tolower [HTTP::path]] {
"*.css" -
"*.pdf" -
"*.txt" -
"*.flv" {
 Select the Apache pool for static filetypes
pool Apache_Pool_80
}
"/webservices*" -
"/qas*" {
pool Weblogic_Services_Pool
}
default {
 Select a pool for non-matching filetypes
pool some_default_pool
}
}
}

Another reply on its way.

Here's an updated version of your approach:

when HTTP_REQUEST {
if {[class match -- [string tolower [HTTP::path]] ends_with images] } {
pool Apache_Pool_80
} elseif { ([HTTP::path] ends_with ".gif") || ([HTTP::uri] ends_with "/qas") } {
pool Weblogic_Pool
} elseif {[HTTP::uri] starts_with "/webservices" } {
pool Weblogic_Services_Pool
} elseif {[HTTP::uri] contains "/atgws" } {
pool buybuybaby.com_services_80
} else {
pool Apache_Pool_80
}
}

All,

 

This was an issue with persistence not http classes. Issue resolved.

 

Thanks,
