Review Comment:
   swoc::TextView looks good, I could not get `tv.rtrim_if(&isspace)` to 
compile, i went with this instead
   
   ```c++
   std::string_view
   strip_params(std::string_view v)
   {
     swoc::TextView tv{v};
     tv = tv.take_prefix_at(';');
     tv.rtrim(swoc::CharSet(" \t\n\r\f\v"));
     return tv;
   }
   ```
