when HTTP_REQUEST {
if { [string tolower [HTTP::host]] equals "test.domain.com" } {
switch -glob [string tolower [HTTP::uri]] {
"/y/z*" {
return
}
"/y/*" {
if { [TCP::local_port] ne "443" } { HTTP::redirect "https://[HTTP::host][HTTP::uri]" }
}
"/y*" {
if { [TCP::local_port] ne "443" } { HTTP::redirect "https://[HTTP::host][HTTP::uri]" }
}
"/*" {
if { [TCP::local_port] ne "80" } { HTTP::redirect "http://[HTTP::host][HTTP::uri]" }
}
default { drop }
}
