From a SSH client (Windows) or Terminal (OS X) window, you will need to connect to your site account's home directory on the panel server via a SSH connection:
Code Block language bash ssh <utw10NNNNN>@panel.utweb.utexas.edu
**NOTE: These next steps assume that you are still in your home directory and have not changed your working directory upon logging in.Copy the clearcache.sh file in to your site account's home directory: To do this, type the following in to your command line:
Code Block language bash cp /utweb/common/src/examples/clearcache.sh clearcache.sh
Now that the file is in your home directory, we need to change the permissions of it to be executable. To do this, type the following in to your command line:
Code Block language bash chmod 750 clearcache.sh
Now that the file is executable, run the script by typing the following in to your command line:
Code Block language bash ./clearcache.sh OR **If your site has been stamped with a vanity domain(s), then you can supply them as arguments to the script. Be sure to include a space between each domain, and if your site is accessible with www, be sure to include that as well. ./clearcache.sh [domain] [www.domain]Real Output:

Check to see if the proxy caches were flushed by typing this in to your command line:
Code Block language bash curl -vI utwNNNNN.utweb.utexas.edu OR curl -vI <your vanity domain here>Real Output:

Pay attention to the bottom of the output where you will see something like this to confirm the cache was flushed on that proxy cache server:
No Format < X-Cache: MISS X-Cache: MISS
