Subject [users@httpd] Updating directory content
Date Mon, 25 Nov 2013 06:51:49 GMT
My Apache server is used for downloading files via HTTP (Linux).
I have a directory tree containing all the files.
The files are updates from time to time by a different process.
I am worried that Apache Web server will read from the file while the other process is writing
to the file.
What is the best method for synchronizing the two processes? Is there a built in mechanism
in Apache?
A few options I thought of:
                Symbolic links for rotating between current file and updated file
                Aliases in Apache configuration files for rotating between current file and
updated file. Use reload for telling Apache to refer to updated file. However, I do not know
if the reload waits for all threads to read new configuration.
Would appreciate any consult.
