Hi all, I am new to Java Servlet programming. I understand GET requests represent when a user fills out a form on html. POST request can be used when the information sent by the client will update or change a database in some way. Can someone tell me what HEAD requests are used for? In html, <head></head> tags are used to give the website a title. How are HEAD requests used in Servlet programming? Also why would a client want to see only the headers of a response? Are Headers in Servlet programming referring to <head> </head> in HTML? What about the <meta> tags in between <head> tags in HTML? Do servlet programs manipulate these tags?
The headers referred to are part of the HTTP protocol, not the <head> tag contents of a page. By looking at the Last-Modified value in the response, a browser can decide whether or not to use cached data. Bill
