NimbostratusiRule to redirect if querystring matches list
Hi I have a request to redirect users to a different URL for matching parameters. For example;
Current URL: https://xxx.domain.com/Foo/Bar?aa=NNNNNNN
New URL: https://yyy.domain.com/?aa=NNNNNN
Where NNNNNN is a unique identifier.
I would ideally like to hold a list of these NNNN's in a Data Group and redirect sessions if NNNNNNN matches a item in a Data Group.
Any pointers would be much appreciated.

You can use a URI::query to get a parameter value:

Use the class command to work with a datagroup:

Both links have iRules examples at the end of the page, so you just need to take the code part you need and create your iRule.

Please validate below iRule. Hope it will work.
class redirectURIs { NNN AAA BBB } when HTTP_REQUEST { if { [matchclass [URI::query [HTTP::uri] aa] equals redirectURIs] } { HTTP::respond 302 Location "https://yyy.domain.com/?aa=[URI::query [HTTP::uri] aa]" } }
