class match/data group - uri pool selection failing...

Hello,

I have an iRule that is giving me some trouble. I created a string datagroup of several URIs. The goal is just to look for a match on a particular URI and then send to the pool if a match is found. Otherwise, send the request to the landing page. The LTM is running 10.2.0 1707.15. For some reason, EVERY reqeust always goes to the landing page. A match is never found. The first line in the datagroup is another option I was trying. Any help would be very much appreciated.

when HTTP_REQUEST {

if { [class match [string tolower [HTTP::uri]] starts_with DMPS_URI_List] } {

pool DMPS_Stage_88

}

else {

HTTP::redirect "https://apps.company.com/"

}

class DMPS_URI_List {

{

"bpptasks" { "apps.company.com/bpptasks/" }

"dpptsks"

"jpptasks"

"lpptasks"

"gpptasks"

"mppatasks"

"opptasks"

}

Thank you,

Correction, with this datagroup, the URIs are not parsed correcly and it always goes to the landing page, regardless of the URI. Right now I have been testing with /bpptasks mainly. Any idea why the URIs are not being parsed correctly???

class DMPS_URI_List {

{

"/"

"/bpptasks" }

"dpptsks"

"jpptasks"

"lpptasks"

"gpptasks"

"mppatasks"

"opptasks"

}

}

The / entry is potentially going to match every request as all local URIs will start with /. Try removing that one and then test the others. If you're still not seeing the results you're expecting, try putting in a log statement under the pool statement and the else statement.

Ok, I removed the single "/" entry. I also tried adding two slashes such as //bpptasks/ but it made no diffference. When I log for a match and for the redirect, I get no matches. It just sends everything to the landing page and never matches on a URI.

Do we know if this is a bug in 10.2.0 1707.15?

Can you paste the current rule/datagroup again?

Here is the current version:

when HTTP_REQUEST {

if { [class match [string tolower [HTTP::uri]] starts_with DMPS_URI_List] } {

pool DMPS_Stage_88

log local0.info "Match found for [HTTP::uri]"

}

else {

HTTP::redirect "https://apps.company.com/"

log local0.info "NO Match found for [HTTP::uri]"

}

}

class DMPS_URI_List {

{

"//bpptasks"

"//dpptasks"

"//jpptasks"

"//lpptasks"

"//mpptasks"

"//opptasks"

}

}

You'll want to remove one of the leading forward slashes from the datagroup entries.

I've already tried that. I started out with a single leading slash but it made no difference so I began experiementing. I will remove the leading slashes right now though.

Any more ideas?
