    To negate starts_with I would use the not operator:

    https://clouddocs.f5.com/api/irules/not.html

    when HTTP_REQUEST {
  if { not ([HTTP::uri] starts_with "/abc") } {
     # do something ...
  } else {
     # do something else...
 }
}

    For excluding the exact path, you can go with  the "ne" operator

Thank you all for responding to my post. I have another question.

What would be right syntax if I need to use 2 URLs?

if { [HTTP::path] ne "/abc/Web123/cde/forum123" OR "/abc/Web123/cde/forum456"

Is the "OR" correct operator?

Thank you!

For the requested logic, you need the "and" operator between two tests:

if { ([HTTP::path] ne "/abc/Web123/cde/forum123") and ([HTTP::path] ne "/abc/Web123/cde/forum456") }

 If you plan to add more paths in the future, then consider using a switch test
