NimbostratusiRule Question
Hi everyone, this is my first time using Data Group lists and I'm having some trouble with the below iRule. Does anyone have any suggestions on what I might be doing wrong?
Also a summary as to what the iRule is doing. Basically if you are trying to go a URI other than one on the "approved" data group list, you get redirected back to the root level of the site.
when HTTP_REQUEST {
if { [[HTTP::uri] starts_with a_string] } {
pool some_pool
}
else { HTTP::redirect "https://somedomain.com/" }
}
This should do the trick. Just make sure your DG is a string list and your /URIs go in the string field.
when HTTP_REQUEST { if { [class match [HTTP::uri] starts_with "/Common/"] } { pool some_pool } else { HTTP::redirect "https://somedomain.com/" } }

Brad, you'll need to use the class command to reference the data group.
See the following wiki for examples, specifically using "class match"

when HTTP_REQUEST { if { [class match [HTTP::uri] starts_with "/Common/"] } { pool some_pool } else { HTTP::redirect "https://somedomain.com/" } }- Brad_Parker_139probably want to [string tolower [HTTP::uri]] to make sure your matching is all lower case.
- Brad_146558Unfortunately it still seems like it isn't matching against the datagroup and forwarding all URIs on to the pool.
- Brad_Parker_139Removed the erroneous extra } from the rule above.

Brad - looks like the iRule above has too many } but it would error when creating the irule so can i assume you've removed one of these.
Anyway, what does your DG look like. I tested the irule above with the following DG and it worked just as Brad Parker suggested.
Here's my DG
ltm data-group internal uri_allowed { records { /test { } } type string
