Hello CraigyB, Try using the following iRule.

when HTTP_REQUEST {
if { ( [string tolower [HTTP::uri]] starts_with "/info" ) } {
    set uri [HTTP::uri [string map {"/info" "/files"} [HTTP::uri]]]
    HTTP::redirect "https://[HTTP::host]$uri"
}
}

    i've tested the following and it's working fine.

    when HTTP_REQUEST 
if { ( [string tolower [HTTP::uri]] starts_with "/info" ) } {
set newUri [string map [list "info" "files"] [HTTP::uri]]
HTTP::redirect "http://[HTTP::host]$newUri"
}

    if you want to replace the host/port , change the redirection part from HTTP::redirect "http://[HTTP::host]$newUri" to HTTP::redirect "http://10.10.10.10:9000$newUri"
