This file wasn't included in commit 4af40b3646d3b09 which updated all
haxx.se http urls to https. The file was committed prior to that update,
but may have been merged after it and hence didn't get updated.
Closes#2550
You'll find a mix of various documentation in this directory and
subdirectories, using several different formats. Some of them are not ideal
for reading directly in your browser.
If you'd rather see the rendered version of the documentation, check out the
curl web site's documentation section for
general curl stuff or the libcurl section for
libcurl related documentation.
