htaccess - How to force the client's browser to clear the cache?

Question

For my site I have the following htaccess rules:

# BEGIN Gzip

AddOutputFilterByType DEFLATE text/text text/html text/plain tex         


        

Answer 1

The most straight forward is to add filetime to the request. eg

myfile.txt?2014-10-30-13:12:33

versioning by date.
