Jonathan Hunter created GUACAMOLE-506:
-----------------------------------------

             Summary: Printing does not work via HTTP, only via websocket
                 Key: GUACAMOLE-506
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-506
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-client, RDP
    Affects Versions: 0.9.13-incubating
            Reporter: Jonathan Hunter


Printing does not work (for me, at least) when using guacamole via an Apache reverse proxy *in HTTP mode*. I think that this counts as a bug - since everything else i.e. normal interactive use of guacamole RDP/VNC/SSH/etc. sessions work fine in this configuration, i.e. without websockets, just http reverse proxying.
 
The following two steps got printing going for me, but I think printing _should_ work via HTTP...  * Install Apache's mod_proxy_wstunnel (on Debian this is 'sudo a2enmod proxy_wstunnel')
 * Add a line in Apache's config to websocket-proxy the relevant URL. (Note that this line must come *before* the config entry that proxies the rest of guacamole, since Apache's ProxyPass command operates on a first match wins basis.)

 
(I did look at Chapter 4 of the documentation, and in particular the 'Proxying with websocket' section, but I found I did not need the ProxyPassReverse statement shown there; nor did I need to place it within a <Location> section, in my config at least.)
 
My Apache config now looks like this:
{quote}{{        ProxyPass /remoteaccess/websocket-tunnel        {color:#d04437}ws{color}://docker.host:5678/guacamole/websocket-tunnel}}
{{        ProxyPass /remoteaccess/                       {color:#d04437} {color}[{color:#d04437}http{color}://docker.host:5678/guacamole/]}}{quote}
 
and printing now works perfectly.
