Hi,can someone do me a favor on "&"

In this case, "&" is a separator of "field=value" pairs in query_string, and not a bit-wise AND operator.

 

 

URI may contain a query string as follows:

 

 

/secl/format?field1=value1&field2=value2

 

 

So, your command is adding a field "bigip" with value of "0" to HTTP::uri string.
