CirrostratusURL PATH based routing
Hi,
wondering if someone can help me here with a basic IRule that routes traffic to a particular pool based on matching a FQDN and URL path?
The reason for this is that the same FQDN is used for multiple services.
e.g. this is what I use in riverbed world but I have not cracked the Irules yet:
if(string.startsWITHl( http.getheader ( "Host" ), "abc.com" ) ){
if(string,contains(http.getpath(), "/test.svc")){
pool.use( "abc_pool" );
} else if(string,contains(http.getpath(), "/efg.svc")){
pool.use( "efg_pool" );
will really appreciate your help with this.
Regards,

when HTTP_REQUEST { switch [HTTP::host] { "abc.com" { switch -glob [HTTP::uri] { "/test.svc" { pool abc_pool } "/efg.svc" { pool efg_pool } } } } }
Qasimthanks Snl, just tested but I am getting the following error while saving it:

actually ignore me, I was making a typo in the rule. apologies
I will let you know once i have tested the service.

just wondering though, what would my Irule look like if I was to merge the following two Irules into one:
- when HTTP_REQUEST {
- switch [HTTP::host] {
- "abc.com"
- {
- switch -glob [HTTP::uri] {
- "/abc.svc" { pool abc_pool }
- }
- }
- }
- }
- when HTTP_REQUEST {
- switch [HTTP::host] {
- "efg.com"
- {
- switch -glob [HTTP::uri] {
- "/efg.svc" { pool efg_pool }
- }
- }
- }
- }
in the above two rules the fqdn is different as well

Hi,
Apologies it was my bad. I was making a typo i the rule. so what's your though about the below:
what would my Irule look like if I was to merge the following two Irules into one:
- when HTTP_REQUEST {
- switch [HTTP::host] {
- "abc.com"
- {
- switch -glob [HTTP::uri] {
- "/abc.svc" { pool abc_pool }
- }
- }
- }
- }
- when HTTP_REQUEST {
- switch [HTTP::host] {
- "efg.com"
- {
- switch -glob [HTTP::uri] {
- "/efg.svc" { pool efg_pool }
- }
- }
- }
- }
in the above two rules the fqdn is different as well
- Snl
try below
when HTTP_REQUEST { if { [string tolower [HTTP::host]] eq "abc.com" and [HTTP::uri] contains "/abc.svc" } { pool abc_pool return if { [string tolower [HTTP::host]] eq "xyz.com" and [HTTP::uri] contains "/efg.svc" } { pool xyz_pool return } } }

Probably something like this
when HTTP_REQUEST { switch [HTTP::host] { "abc.com" { switch -glob -- [HTTP::uri] { "/abc.svc" { pool abc_pool } } } "efg.com" { switch -glob -- [HTTP::uri] { "/efg.svc" { pool efg_pool} } } } }- Qasim
thanks Eehir/SNL, I have tried this now, I will let you know once I have a confirmation.
much appreciated

.Hi Eehir,
Can you help out here please. your rule works as expected but the problem is that its locking it down to that specific path. any chance we can change rule to say the "starts with" if so, would that fix the problem? if so, how the rule would look like?
thanks in advance.

Hi,
Just add * to the end of the path, that should act as a starts with statement.
/abc.svc*
- Qasim
thanks guys,
the rule is working as expected but its locking it down to that specific path. any chance we can change this to e.g. "http path starts with" or contains? whatever you think is better
kind regards,
