User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2 When starting Firefox, a request is made to retrieve the feed for each livemark. This request is sent without an If-Modified-Since HTTP header, causing the full feed to be retrieved. Not sending an If-Modified-Since header causes extra load on servers as feeds are retrieved each time a user starts Firefox. Some sites will ban clients automatically if too many requests are sent (http://slashdot.org/faq/accounts.shtml#ac1050). It also means more bandwidth is consumed on the client than is absolutely necessary (a particular problem for dial-up users - see bug 287341). Reproducible: Always Steps to Reproduce: 1. Add a livemark. 2. Close down all Firefox windows. 3. Open Firefox with a packet sniffer running in the background. Actual Results: A request is made for each feed with no If-Modified-Since header. Expected Results: The last modified date of each feed should be stored. This date should be sent in an If-Modified-Since header so that only feeds that have changed are downloaded. Better still, it would be good if Firefox could only make requests for feeds that are due a refresh anyway (i.e. making sure sites are only polled at their update frequency).
