Why isn't url-http-end-of-headers set correctly when using url-automatic-caching?

2017-05-19 16:18:21

This is a follow-up question to How can I make url.el work with the If-None-Match header?

Evaluate the following form:

(let ((url-request-method "GET")

(url-automatic-caching t))




(message "'%c' (%S)"

(char-after url-http-end-of-headers)


It thinks url-http-end-of-headers is position 1 in the following buffer:

  • This seems to be a bug in emacs at url-cache-extract with its use of erase-buffer and wooing out that marker. More details when I'm not mobile. I'll be submitting a bug report :-)
