Hi, The app has an instance of Apache (2.2.13) load-balancing a 2-instance cluster of JBoss EAP 4.3.0.GA_CP06 running a web application. Apache and JBoss are connected via mod_proxy_ajp. Intermittently, the web server will return an html page with a mime type of text/plain, causing it to display as source (in Firefox; IE seems immune). Also, and I believe these are related to the first problem: intermittently, the web server will fail to redirect the browser, resulting in a blank page, and sometimes images will fail to display (these are not browser-specific). Any ideas? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263216#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
