With a fulfilled request, the server sends a Last-Modified (or ETag) header. For results the client caches, the client keeps track of that value. If the client requests the resource later, it sends an If-Modified-Since (or If-None-Match) header with its request. https://stackoverflow.com/questions/20978189/how-304-not-modified-works https://tools.ietf.org/html/rfc7232 > An entity-tag can be more reliable for validation than a modification date in situations where it is inconvenient to store modification dates, where the one-second resolution of HTTP date values is not sufficient, or where modification dates are not consistently maintained. ``` 🐚 falstaff ~ $ curl -I https://paulgorman.org/technical/blog/rss.xml HTTP/1.1 200 OK Server: nginx/1.12.2 Date: Fri, 02 Aug 2019 15:22:39 GMT Content-Type: text/xml; charset=UTF-8 Content-Length: 49006 Last-Modified: Tue, 30 Apr 2019 21:29:18 GMT Connection: keep-alive ETag: "5cc8be2e-bf6e" Accept-Ranges: bytes 🐚 falstaff ~ $ curl -I --header 'If-Modified-Since: Tue, 30 Apr 2019 21:29:18 GMT' https://paulgorman.org/technical/blog/rss.xml HTTP/1.1 304 Not Modified Server: nginx/1.12.2 Date: Fri, 02 Aug 2019 15:23:07 GMT Last-Modified: Tue, 30 Apr 2019 21:29:18 GMT Connection: keep-alive ETag: "5cc8be2e-bf6e" ``` Twenty-five-minute walk at lunch.

These include diabetes, high blood pressure, rheumatism and bowel diseases, as well as pain syndromes such as migraines and osteoarthritis. > There are different ways to go about it, but I advise patients to omit either dinner or breakfast, so that they don’t ingest any food for at least 14 hours at a stretch. > When we eat, our body releases insulin. That disrupts the process of autophagy (from the Greek, meaning “self-devouring”), by which cells deconstruct old, damaged components in order to release energy and build new molecules. Autophagy helps to counteract the aging of cells and builds immunity. Fasts stimulate autophagy and allow the full molecular process to take place, as a team led by Frank Madeo at the University of Graz in Austria found in 2017. > Fasting also can contribute to brain health and happiness. The neurobiologist Mark Mattson, who retired this year from the National Institutes of Health, has demonstrated in experiments for two decades that nerve growth factors contribute significantly to brain health and positive mood. He also found that fasting, restricting calories and exercising spur distinct increases in the best-known nerve growth factor, BDNF. > Test animals in Dr. Mattson’s laboratory that fasted intermittently even showed a significantly lower risk of developing Parkinson’s disease, multiple sclerosis and Alzheimer’s, though those results would have to be clearly confirmed in large human studies to reach any firm conclusion.
