- switch to "project authors" style copyright. Instead of an AUTHORS
file (https://opensource.google/docs/releasing/authors/), I just list
Google as a major copyright holder in the README.
- use SPDX style license headers in source files
- remove CLA requirement from contributing docs
This makes the options string more predictable, and easier to compute by
other programs. This is primarily being done to enable signatures that
include option values (see #145).
For now, the options are "jpeg" and "png". Gif is a little harder to
support because of the way we use the image/gif package to handle
animated gifs. I have also have trouble imagining someone wanting to use
gif over png. But if the need really exists, we can address it when it
comes up.
Fixes#89
If imageproxy runs behind an http.ServeMux or certain web servers, the
double slash in the remote URL will get collapsed down to a single
slash. (e.g. http://example.com/ becomes http:/example.com/). This
is now handled by imageproxy directly.
