504 Gateway Time-out The server didn't respond

问题:

The client requested to download a compressed log file, using Ext.js a form submission on an embedded iframe. Request was sent to server, which has Apache and JBoss 6. The servlet compresses log files, do some database operation and returns the compressed file.

Exactly after 2 min, the 504 Gateway Time-out The server didn't respond in time message is seen at the browser net panel. How to fix this error?

回答1:

The servlet was taking a long time to compress the log files, and Apache's timeout was set to 2min.

The error was fixed by increasing the TimeOut Directive on the httpd.conf file:

#
# Timeout: The number of seconds before receives and sends time out.
#
##Timeout 120
Timeout 600

Check your apache error logs. This can also be caused if the file size limit is set too low.

In my case more simply. I forgot to disable the Proxy extention in the browser.
