This is an issue with the Apache's Web Server configuration. It sends HTTP headers to prevent 304 responses to If-Modified-Since requests by making all caches never expire (maybe to limit request count and load on servers). Shortly after the announce of the Lucene/Solr release this morning the servers went down again, so there is overload problems.
I can try to "revert" the Apache's own Webserver defaults for Lucene by adding the "real default" AddHeader settings to .htaccess on Lucene's web page. This would also prevent the always wrong redirect on the download button. I have to try this out, because I am not sure if the header/cache modules are allowed to be used on ASF's main web server from htaccess.
