 This servlet demonstrates how to set response headers, and look
 at request headers.
 It displays a page, with values of all request headers,
-and sends X-Test-Header: header. It also sets Pragma: no-cache
+and sends X-Test-Header: header.
+It displays HTTP method with which this request was made, work of getHeader()
+which returns the value of specified request header(null if there was no such 
+header in HTTP request) and getDateHeader() which returns the number of 
+milliseconds since January 1, 1970 GMT, or -1 if the named header was not 
+included with the request. Throws IllegalArgumentException if the header value
+can't be converted to a date.
+Example provided for If-Modified-Since HTTP request header using testHeaders.pl
+It displays work of containsHeader(), returns true if the named response header
+has already been set, false otherwise. Example provided for X-Test-Header test
+header.  
+It demonstrates work of setDateHeader() by setting "expires" response header to
+the value greater then "modified" response header value to 1 hour. In order to 
+test it, "Pragma" response header must be not set to "no-cache".
