We've been running lighttpd on our image servers for quite some time, but in an effort to speed up page load times, we've been working toward using mod_compress and etags to speed things up.
I've added the following lines to the config:
server.modules = ( "mod_compress" )
#...
etag.use-mtime = "enable"
etag.use-inode = "disable"
static-file.etags = "enable"
compress.cache-dir = "/tmp/lighttpd/cache/compress/"
compress.filetype = ("text/plain", "text/html", "text/css", "text/javascript")
And suddenly no images, css, or javascript are appearing in internet explorer (6 or 7) - google has nothing to say about it. Anyone have any ideas?
