Nimbostratusclass 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,

can u try this one?
class DMPS_URI_List {
{
"/bpptasks" { "/apps.company.com/bpptasks/" }
"/dpptsks"
"/jpptasks"
"/lpptasks"
"/gpptasks"
"/mppatasks"
"/opptasks"
}
} 
John_Ogle_45372I added the slashes but it still fails. Any ideas?- John_Ogle_45372I added the slashes but it still fails. Any ideas?
- John_Ogle_45372Correction, 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.
Aaron- John_Ogle_45372Ok, 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? - Chris_Miller

Can you paste the current rule/datagroup again? - John_Ogle_45372
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"
}
} - hoolioYou'll want to remove one of the leading forward slashes from the datagroup entries.
Aaron - John_Ogle_45372I'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?
