# --------------- esphttpd config options ---------------

# If GZIP_COMPRESSION is set to "yes" then the static css, js, and html files will be compressed with gzip before added to the espfs image
|
|
# and will be served with gzip Content-Encoding header.
|
|
# This could speed up the downloading of these files, but might break compatibility with older web browsers not supporting gzip encoding
|
|
# because Accept-Encoding is simply ignored. Enable this option if you have large static files to serve (for e.g. JQuery, Twitter bootstrap)
|
|
# By default only js, css and html files are compressed.
|
|
# If you have text based static files with different extensions what you want to serve compressed then you will need to add the extension to the following places:
|
|
# - Add the extension to this Makefile at the webpages.espfs target to the find command
|
|
# - Add the extension to the gzippedFileTypes array in the user/httpd.c file
|
|
#
|
|
# Adding JPG or PNG files (and any other compressed formats) is not recommended, because GZIP compression does not works effectively on compressed files.

#Static gzipping is disabled by default.
