But as time passes, e.g. after one hour of looped refreshing the iframe src, the page in iframe just stops responding - it's loading and loading and loading and showing a blank page.
What is strange is that it is only doing with two of my applications (One on Apache 2.2 and One on Tomcat 5.5). Other applications are fine.
I guess it is some configuration stuff, like KeepAlive, MaxKeepAliveRequests or something.
Can anybody tell me what can be the trouble in this case? Can it be the httpd.conf/server.xml configuration thing? Any advises?
