 Currently consensus health has a little arrow next to a relay to jump to
 that fingerprint in the previous hour's consensus. (We store 3 weeks of
 consensuses).

 Clicking the arrow doesn't work, because the html files are stored gzipped
 on the server.  Apache must be modified to enable access to those files.

 Everyone I found was using the same trick to serve compressed content
 through Apache: trick Apache into sending gzip content but not compressing
 it, and then manually adding the gzip header.  I have this deployed on
 http://utternoncesense.com like so:

 {{{
 <VirtualHost [my IPs]>
         ServerName utternoncesense.com
         ServerAlias www.utternoncesense.com
         ServerAlias ipv6.utternoncesense.com

         DocumentRoot /var/www/localhost/htdocs/consensus-health
         <Directory "/var/www/localhost/htdocs/consensus-health">
                Options -Indexes
                AllowOverride All
                Require all granted
         </Directory>

         SetOutputFilter deflate
         Header set Content-Encoding gzip

         <FilesMatch "consensus-health-(.+)\.html$">
                 SetEnv no-gzip 1
         </FilesMatch>

         RewriteEngine On
         RewriteCond %{HTTP:Accept-Encoding} gzip
         RewriteCond %{REQUEST_FILENAME}.gz -f
         RewriteRule (.*\.html)$ $1.gz [L]
 </VirtualHost>
 }}}


 A symlink from a .html to the .html.gz must be present.  If the transfer
 script copies symlinks as files, that would be bad (well, double the size
 needlessly).
