Hi, I am trying to fit Sitemap in our existing J2EE framework as below I have apache web server where all static files sits. Then mod_rewrite redirects the request to Jboss where presentation tier resides. End user make web request to apache webserver through CISCO switches. I have three questions. 1.Can google crawler find sitemap.xml file through switches? 2.Can JBOSS(which is inside firewall) have sitemap.xml or it should sit on apache like www.myweb.com/sitemap.xml? 3.I am going to use content negotiation using apache mod rewrite as below RewriteRule /factsheets/cataracts$ /factsheets/factsheets.jsp?content=cataracts [P,L] And I am going to put URL in sitemap.xml as www.myweb.com//factsheets/cataracts Will this work okay with the crawler? Will this affect google ranking? Please share your experience if you have already used this type of rewrite before. Many thanks, Ashish
