// The BuildHttpGetRequest method is a convenience method for building
// an HTTP GET request.  Normally, an application would use Chilkat's HTTP or REST API's
// for sending HTTP requests.

// 	GET /test.asp?x=123&y=456 HTTP/1.1
// 	Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
// 	Connection: keep-alive
// 	User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
// 	Accept-Language: en-us,en;q=0.5
