Sorry, that’s what I get for not knowing all of the cities and flags (would help if they included that instead of just city names).
Gomez and Keynote both have test locations in Indoa but I’m not sure if they will give you headers for a successful test (I thought Gomez had a proxy solution at one point as well but I could be wrong).
Searching for “http proxy india” provides a fair number of results (some free, all questionable at best :-))
