# Let's Encrypt Webroot Configuration for Apache
#
# In "webroot" mode, the Let's Encrypt client will attempt to write a
# temporary file to the /.well-known/acme-challenge directory within
# the website's root directory in order to perform the domain
# verification.  Since every Vesta site has a different
# web root directory, this directive creates an alias that will allow
# the Let's Encrypt Client to write these files to a central location
# that can be accessed from all sites.

Alias /.well-known/acme-challenge /etc/letsencrypt/webroot/.well-known/acme-challenge

# Ensure that the proper Content-type header is returned with
# challenge responses
<IfModule mod_headers.c>
