Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

example: The following JSON document:  
{"maps":[{"id1":"blabla","iscategorical1":"0", "perro":[{"dog1": "1", "dog2": "2"}]},{"id2":"blabla","iscategorical2":"0"}],
"masks":{"id":"valore"},
"om_points":"value",
"parameters":{"id":"valore"}}

will have the following output:
{'masks.id': 'valore', 'maps.iscategorical2': '0', 'om_points': 'value', 'maps.iscategorical1': '0', 
'maps.id1': 'blabla', 'parameters.id': 'valore', 'maps.perro.dog2': '2', 'maps.perro.dog1': '1', 'maps.id2': 'blabla'}
