# --------------- 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. GZIP_COMPRESSION ?= no # If COMPRESS_W_YUI is set to "yes" then the static css and js files will be compressed with yui-compressor # This option works only when GZIP_COMPRESSION is set to "yes" # http://yui.github.io/yuicompressor/ #Disabled by default.
