Hi,<br>
I have implemented nginx with proxy cache successfully, however, I need<br>
to have the ability to check if a certain file is already cached or<br>
not.<br>
Is there a way to get a list of cached files?<br>
Maybe another way will be to send a HEAD request which contains the file<br>
URI to the proxy cache server to check if a file is already in cache?<br>
<br>
Are these methods possible?<br>
<br>
