Read URL Paramter on application startup in SAPUI5

Hello Gurus,

I think this should be straight forward , So I have index.html file which I call to load my application, Now If I append any other parameters and try that in my browser I get HTTP 404 error.

for e.g. localhost:8080/index.html/?param="XYZ"

So I would like to know what I need to do in my application to enable it to read URL parameters any code example would really be helpful.

Thanks

Somil
