Dear Jason,

I am aware of that. 
However, as the MyRequestParams has multiple fields, we would like to avoid 
implementing the toString method that return a string containing only the URI 
field.
This would break the purpose of the toString method.

Do you know any other approaches/work around for this?

Best
Dat
