NimbostratusThis line set pathcheck [URI::path [HTTP::uri] 2 2] is now throwing this error at run time: "end value (2) not greater than start value (2)"7448 25][URI::path [HTTP::uri] 2 2]
However I do not understand why? Any pointers would be appreciated.
thank you!
CirrostratusOn a local lab F5, I created the simple rule below:
ltm rule testing_URI_path {
when RULE_INIT {
set test_uri "/path/to/file.ext?param=value"
log local0. "\[URI::path $test_uri\]: [URI::path $test_uri 1 1]"
}
}Which resulted in the log output below:

Feb 19 17:49:40 bigip1 info tmm[25355]: Rule /Common/testing_URI_path : [URI::path /path/to/file.ext?param=value]: /to/It looks to me like the form of URI::path with same start and finish values is set to be deprecated in a future release, and while the parser is allowing it now, it's warning about this usage.
You might consider calling F5 support to verify if that's the case.
