Dear All,
My current setup is as following:
User <---> Apache <---> Tomcat
Apache is doing reverse proxy to the tomcat server to serve the site.
I have a request to cache the static files from the tomcat server on the apache files so that after the initial cache, subsequent user requests should hit the cache instead of the tomcat server.
I have the following configuration and files / folders are being generated in the defined cache folder when i access the files hosted in the Tomcat from Apache.
initial request of the files, shows the code 200, if i reload, it shows 304. Not sure if this is because the files are cached in the browser. How can I ensure the static files are being served from the Apache?
Your kind help will be much appreciated

the 304 aka Not Modified. The server tells the browser that the browser has the last version and doesn't need to load it again.
How can you ensure that apache is serving the file and not tomcat?
Compare the log files. |
