NimbostratusRewriting host and part of URI, then appending the remainder of the URI
Trying to create an iRule to bail out my Application people. I need to modify the existing host to be a new host, then modify the "starts_with" portion of the URI, but also append the remainder of the URI for the end-user.
So, http://Server1/ThisURI/end-up-here.htm should rewrite to http://FinalDestination/new/end-up-here.htm
I've architected the following iRule that's not currently working:
when HTTP_REQUEST {
if { (([HTTP::host] equals "Server1") or ([HTTP::host] equals "Server2")) and
([HTTP::uri] starts_with "/ThisURI") } {
HTTP::header replace Host "FinalDestination"
HTTP::uri "/new[string range $uri 8 end]"
}
}
Any help would be much appreciated.
Thanks.
Joe

Do you need to set the uri variable first?
when HTTP_REQUEST {
set uri [HTTP::uri]
......etc

N- Joe_Erchul_4263Nathan,
Thanks for the tip. I added the variables as follows, but still no luck. I don't use variable definition much, so could you check my format for the correct syntax?
Thanks.

when HTTP_REQUEST {
set uri [HTTP::uri]
set header [HTTP::host]
if { (([HTTP::host] equals "Server1") or ([HTTP::host] equals "Server2")) and
([HTTP::uri] starts_with "/ThisURI") } {
HTTP::header replace Host "FinalDestination"
HTTP::uri "/new[string range $uri 8 end]"
}

Without my test bed to double check things do look correct. Here's my iRule with a slight amendment to rule out case insensitivities:
when HTTP_REQUEST {
switch [string tolower [HTTP::uri]] {
set uri [HTTP::uri]
if { (([HTTP::host] equals "Server1") or ([HTTP::host] equals "Server2")) and
($uri starts_with "/ThisURI") } {
HTTP::header replace Host "FinalDestination"
HTTP::uri "/new[string range $uri 8 end]"
}
}
}
What happens if you do a curl -i http://Server1/ThisURI/end-up-here.htm -what response do you get back?
