The following irule is a way to add a cookie header signifying a location of where the application is hosted. This can be used by CDNs such as Akamai that need to know the location of the requests if you have a distributed content hosting model.
Code :
when HTTP_REQUEST {
set urihead [HTTP::host]
# set the value for location in the cookie
set loc [HTTP::cookie "location"]
}
when HTTP_RESPONSE {
# checks to see if there is a west location or a no cookie value
# If you want to check if there is a east location
if { $loc == "" } {
HTTP::cookie insert name "location" value "west"
HTTP::cookie expires "location" 1209600 relative
HTTP::cookie path "location" /
HTTP::cookie domain "location" $urihead
}
}
