+
+This is a one time task. Proposed caching is 3 months for all but `MathJax.js` which gets 1 week.

+
+This is theoretically risky. Since caching can only be specified after making the file public, it could theoretically happen that MathJax.js is called and cached before the second command runs -- fixing it to a 3 month caching that cannot be undone.
+
+Well, it didn't happen. So we're good.

 ## TODO
 
-* tests -- we don't actually have any tests that check the functionality of the CDN.
-   * CORS
-   * mimetype
-* change caching time. Something like 
+* tests.
+   * CORS [vital]
+       * A simple test: switch mathjax.org over to the origin. user browsershots/browserstack etc to check rendering across IE, FF, Chrome, Safari.
+   * mimetype [non-vital]
+      * write script to `curl -I` all woff and otf files, compare header.
 
-        $ gsutil -m setmeta -r -h "Cache-Control:public, max-age=7776000" gs://mathjax-cdn/mathjax/
+* swich over to new container `mathjax` (no idea why mathjax-cdn was chosen the first time around...)
 
-but we don't want to apply this to MathJax.js. Not sure how to do this efficiently.
