No because you dont need to close connections. Whats the main objective here? Why are you trying to unset variables? If its important to unset variables for your application then use a prefix for ones you need to unset.

An application with seven vars needs to unset four of them. These vars use an underscore prefix so they are _var1 _var2 _var3 _var4 _var5 so the following one line command can be used to unset them. 

unset [info vars _*]

If they are not always defined add -nocomplain to the unset command to prevent it logging errors.
Info is a very useful command - Tcl - info (n) (princeton.edu)

Hello Kevin,

-> No because you dont need to close connections. Whats the main objective here? 

I am using these in the irule when detecting HTTP 404, 503 and 504

 
   TCP::close
    event disable all

I now understand that "  event disable all" is what I need, because, when I have those HTTP status responds, I don't want the rest of the irule to be process, also, because I already use "HTTP::respond"  to respond the "error message".

The only problem left here is should I really use the TCP::close when I have  "event disable all" after, I guess it is need so that It can release the memory afterward.

Thanks for your explaination.
