What is the best way to view the HTTP response headers from a request against a particular URL? Telnet or is there some other really good command or tool?
I use the httpfox Firefox extension to view all HTTP requests and responses (including header and body) initiated from the web browser in the interval I specify (by pressing the start-recording and the stop-recording buttons). httpfox presents the data in a structured way in which I can quickly find the request I am interested in. It nicely complements LiveHTTPHeaders, because httpfox can view requests in the past as well.
