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
- If you have vanity domains stamped on your site, then please follow these instructions to add those to the script; otherwise, proceed to step #8:
Type the following command in your command line to edit the clearcache script:
Code Block nano ~/clearcache.sh
This will bring up the nano text editor in your terminal window. From here, you will need to navigate the file with your keyboards arrow keys. Find the line that says urlstopurge="$site"
Once you have navigated to that line, put a space after $site and add the domains you have stamped with your site. separate Separate each entry you add with a space. If your site can be visited with www, please include that name as well.
- When you are finished adding your domains, press "Ctrl+o" on your keyboard. Nano will then repeat to you the file it is making these changes to. Press "Enter" on your keyboard to confirm the file and save your changes.
Now that the file is in your home directory (and your domains have been optionally added), we need to change the permissions of the script to be executable. To do this, type the following in to your command line:
Code Block language bash chmod 770 ~/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
Real Output (no additional domains have been added to the script, so the cache is only being cleared for utw10373.utweb.utexas.edu):

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
