Pragma: no-cache is a request directive, not a response directive. The ETag doesn't change between negotiated representations. An If-None-Match conditional request returned the full content unchanged. An If-Modified-Since conditional request returned the full content unchanged. The If-Modified-Since response is missing required headers. The Range response is missing required headers. A ranged request returned partial content, but it was incorrect. Cache-Control: public is rarely necessary. This response allows a cache to assign its own freshness lifetime. :: Most of these errors occur in the script URLs that run the dynamic parts of the pages and the videos. It is a mess. Software attempting to use any of the _common_ HTTP/1.1 features (Range requests, If-modified requests, ETag unique content identifiers) is screwed. > > Of the two Squid boxes I have at two different locations that experience > this issue, the versions are: > Squid Cache: Version 3.2.9 > Squid Cache: Version 3.2.11 > > I've pruned both the squid.conf to very basic configurations at both > locations and I can't get these sites to work. > > Can anyone confirm they have the issue or don't have the issue or perhaps > provide insight? Thanks in advance! Confirmed *without* using Squid. I get the same errors on those pages in my browser without a proxy at all. I also get errors where it tells me I need to install flash player, which is already installed and on previous request for the same *exact* videos just worked perfectly. I am not very hopeful about anything short of the authors fixing their web server will fix this. Amos
