RFC2616 (10.3.3 302 Found) says as follows: Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). In case HTTP redirect response is created without sendRedirect, servlet developers are responsible for its header and body. However, when calling sendRedirect, body with a hyperlink should be included in the response.
Should == optional == enhancement
Fixed in trunk and 7.0.x and will be included in 7.0.21 onwards. I do not plan on back-porting this to 5.5.x and 6.0.x.
