I wrote a simplified variant of your iRule. Tested and works as expected.
when HTTP_REQUEST {
if { [HTTP::host] equals "www.myfancydomain.com" && [HTTP::uri] starts_with "/test" } {
node 10.100.153.40 3000
}
}
Note that I am matching the HTTP::host with equals, not with contains, because HTTP::host should be an exact match anyways.
Also I used HTTP::uri instead of HTTP::path and, but more important, I use starts_with, because HTTP::uri might also be /test/image1.jpg, test/index.html...
And since you are always matching the same HTTP::host value, you might want to remove that check from your iRule logic and go for a switch statement to only match the HTTP::uri. Something like this.
switch -glob [HTTP::uri] {
"/foo*" {
# this will match on any string that starts with "/foo"
}
"*bar" {
# this will match on any string that ends with "bar"
}....
Thanks for the code . it work for "/m2p" and other NOT working . Now I removed RETURN at the end of each NODE . Looks likes its Working . I am doing more TESTING .
Can you please ADVISE on this Irule .
when HTTP_REQUEST {
if {([string tolower [HTTP::host]] equals "test-esb-vip-bma.bhp.com") } {
Yes, you had strictly defined your URI path at the first attempts : "eq". Please note that the last script states "start with" which offers more flexibility...but less security.
Ok , i ran into problem . The iRULE work fine but the requirement is to replace the host header from test-esb-vip-bma.example.com/m2p to a new url "www.newurl.com/m2p when the LB initiate the request to the server end .
what is mean to say is for example as per the irule /m2p is pointing to node 10.30.214.1 2783 . So when the LB initiate the HTTP Get request , it rebuilt the URL with new HOST 10.30.214.1 with URI /m2p . Is this achievable ?
I am trying to TWEAK my irule . Any help in this regard how to replace the HOST header when the LB initiate the request and change with NODE IP AND PORT and append the URI ?
I am currently Working towards to get friendly with IRULES . Really sorry for hitting with many question . My bad 😐
There are like 200 URLS served from different HOSTS ( around 8 or 9 in nos ) . we want to ROUTE the application based on URI PATH which we discussed with ABOVE iRULE .
