Unfortunately, HTTP proxies are kind of a thing of the past. Back when I wrote it, it was easy to implement a proxy (HTTP 1.0 with some HTTP 1.1 features). Now there are two issues. The smaller one is that you have to handle a lot of complexity from HTTP 1.1. The bigger one is that increasing use of HTTPS (a good thing!) means that things like caching, ad-blocking, and history search absolutely have to be in the browser. The author of Polipo, one of the best caching proxies, has declared it obsolete for this reason. It would be a good feature for the deluxe Pinboard subscription. As long as you're mirroring the content, you might as well index it with Lucene or something.
