+### Enable gzip Compression for All Files Except for Images
+This enables gzip compression for all files in the folder except for the images. Images are already compressed and re-compressing them is just waste of resources.
+``` apacheconf
+SetOutputFilter DEFLATE
+SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|bmp|tiff)$ no-gzip dont-vary
+```
+
+### Disable gzip Compression
+This disables gzip compression for the folder.
+``` apacheconf
+SetEnv no-gzip 
+```
+
+### 1 Day Caching
+Allows the contents of the folder to be cached for one day. This can be adjusted to any different number of seconds.
+``` apacheconf
+Header set Cache-Control "max-age=86400, public"
