Unsanitized URI breaks TCL

I have an iRule which relies on a switch statement: when HTTP_REQUEST { switch -glob [HTTP::uri] { (do stuff) } } It appears that some requests result in the error in /var/log/ltm: ...

You can avoid that TCL error by using two hyphens to terminate the switch flag:

 

 

switch -glob -- [HTTP::uri] {

 

 

That will avoid the TCL runtime error and TCP reset. The request still looks like garbage though so don't expect it to match a non-default switch case.
