Answer 1

From MSDN:

The QueryString collection retrieves the values of the variables in the HTTP query string. The HTTP query string is specified by the values following the question mark (?).

In your case the QueryString collection would contain five members: center, zoom, size, maptype, sensor. Retrieve them like so:

Request.QueryString("center")

Similarly for the other variables as well.

You can use Server.UrlEncode() method to produce save string for use in url. For example :

string queryString = "http://maps.googleapis.com/maps/api/staticmap?center=34.0833869772674,74.7986488044262&zoom=21&size=550x450&maptype=roadmap&sensor=true";
Response.Redirect("http://www.mysite.com/?imgName=" 
                    + Server.UrlEncode(queryString));
