CirrusURL/URI rewrite without changing in Client browser
Hello All Experts, Greetings! I have an issue where I need to rewrite URL and as well as URIs from https://abc.com/xyz to https://pqr.com/mnp. I found two ways to do that one I can use a profil...
I'd maybe argue that partitions aren't create separate logical BIG-IPs. It's more about building separate administrative domains on a single BIG-IP. Further, partitions can always access the /Common partition. To answer your question though, it depends on the level of isolation, but you should simply be able to point to the VIP in the oter partition,
virtual "/abc-app-dev/np-api-vip" or virtual "/Common/abc-app-dev/np-api-vip"You don't need SNAT to communicate between VIPs on the same BIG-IP.
Hi Kevin,
Thanks for your guidance. Here is what I figured out and it is working now. All happened due to your idea so thanks again.
IRule for same routing domain :-
when HTTP_REQUEST {
log local0. "Incoming request: [HTTP::host]:[HTTP::uri]"
if { [set match [class match -value -- "[HTTP::host]:[HTTP::uri]" starts_with datagroup_Name]] ne "" } {
log local0. "Datagroup match: $match"
## Get first URI path in client request
set FIRSTPATH [getfield [HTTP::path] "/" 2]
## Split match into host and path
set matchlist [split $match ":"]
set MATCHHOST [lindex $matchlist 0]
set MATCHPATH [lindex $matchlist 1]
## Replace FIRSTPATH with MATCHPATH (from full HTTP::uri)
set UPDATEDPATH [string map [list "/$FIRSTPATH" "$MATCHPATH"] [HTTP::uri]]
log local0. "Updated host: $MATCHHOST"
log local0. "Updated path: $UPDATEDPATH"
HTTP::host $MATCHHOST
HTTP::uri $UPDATEDPATH
virtual "/path/virtual_server_name"
}
}For different route domain
when HTTP_REQUEST {
log local0. "Incoming request: [HTTP::host]:[HTTP::uri]"
if { [set match [class match -value -- "[HTTP::host]:[HTTP::uri]" starts_with datagroup_name]] ne "" } {
log local0. "Datagroup match: $match"
## Get first URI path in client request
set FIRSTPATH [getfield [HTTP::path] "/" 2]
## Split match into host and path
set matchlist [split $match ":"]
set MATCHHOST [lindex $matchlist 0]
set MATCHPATH [lindex $matchlist 1]
## Replace FIRSTPATH with MATCHPATH (from full HTTP::uri)
set UPDATEDPATH [string map [list "/$FIRSTPATH" "$MATCHPATH"] [HTTP::uri]]
log local0. "Updated host: $MATCHHOST"
log local0. "Updated path: $UPDATEDPATH"
HTTP::host $MATCHHOST
HTTP::uri $UPDATEDPATH
pool pool_name
}
}

CirrusHi CA_Valli,
How to incoroprate the different paths with the use of datagroup in the iRule provided above. Also when the response would come back doesn't it need to be changed to original URL+URI/path as well?
Thanks,
Prasenjit

MVPI've tried to modify my syntax, haven't had the chance to test it in a lab so please be careful with this and don't run it in prod without testing.
Code below is supposed to replace anything that matches /aaa/ /bbb/ or /ccc/ at depth1 in your path (this is driven by "starts_with" condition) with static /mnp/
so /aaa/path/to/index.jsp will change into /mnp/path/to/index.jsp/
and i believe /bbb/bbb/file.txt should change to /mnp/bbb/file.txt
Please also integrate knowledge shared by Kevin_Stewart in his comments which is very detailed and much more reliable than my attempt 🙂
Lastly, I don't think you will need to change anything in HTTP response.
when HTTP_REQUEST {
set uri [HTTP::uri]; set path [HTTP::path]; set query [HTTP::query]
HTTP::header replace Host "pqr.com"
if {[class match $path starts_with datagroup_rewriteURL]} {
set dgValue [class match -value $path eq datagroup_rewriteURL] ; #i believe this should return /xyz/ if you've set as a string entry in the data group
log local0. "replacing $dgValue with /mnp/"
set newpath [string map -nocase { $dgValue "/mnp/"} $path]
HTTP::uri "$newpath$query"
}
}
ltm object will be something like
ltm data-group internal datagroup_rewriteURL {
records {
/aaa/ {}
/bbb/ {}
/ccc/ {}
}
type string
}
