Hi. I'm having some intermittent issues with the Apache mod_deflate
compression. When I have compression turned on (please see my configuration
snippet below), my pages load fairly slowly and I occassionally receive a popup
prompt to save the page because it's been returned as type
"application/octet-stream". When I turn off the compression, everything is
fast and perfectly normal.
It appears, although I'm not 100% certain (and I hope this isn't a red
herring), that it may be related to situations in which Apache returns an HTTP
Response Code 304 for javascript or CSS files. It seems that the 'text/html'
content is coming back fine, but JavaScript and CSS have troubles.
I'm using Apache version 2.0.59 on Linux Red Hat and Firefox 1.5.0.11 on
Windows. Has anyone else experienced anything like this? I haven't been able
to find an answer to this problem yet. thanks!
