Should append latitude,longitude,altitude,radius parameters to existing custom URL that contains parameters

[GoogleCodeExporter]

What steps will reproduce the problem?
1. When updating custom datasource to: 
http://myapi.com/rest/v1/public/events?format=mix

2. Mixare sends: 
..../events?format=mixare?latitude=38.89965711&longitude=-77.02150975&altitude=7
2.0&radius=20.0 
3.

What is the expected output? What do you see instead?
The code should be updated to detect if parameters already exist,in the URL, if 
they do use '&', instead of always '?"
results should be:
/events?format=mixare&latitude=38.89965711&longitude=-77.02150975&altitude=72.0&
radius=20.0 

What version of the product are you using? On what operating system?

Please provide any additional information below.
