DataTables Search box blocking backspace key?

Working with DataTables for the first time I was having some issues with the UI. The search textbox was not allowing the user the backspace. They were able to select the text and use the delete key to clear it out, but it almost felt like there was a script capturing and suppressing the backspace key press. Upon closer inspection the “type” of the input was “Search”. According to w3schools (and Visual Studio’s Intellisense) this was valid HTML. The example of their site worked as well. Perhaps it had something to do with the other scripts running on the page, or possibly the Bootstrap library addon for DataTables? Changing the type to “Text” fixed the issue. I found an easy workaround here until I can fix the root of the problem.

Proxying Apache Connections to Multiple Applications

I was having issues getting Apache working with Plex, OwnCloud, and SyncThing at the same time on a new server. I wanted to have a reverse proxy set up, so instead of

I could have

Apache’s reverse proxy functionality caters to this need.
Each app gets its own ProxyPass, telling Apache what to do with incoming requests.
SyncThing didn’t like operating without a trailing slash in the URL, so a rewrite rule was created to do this for the user.
OwnCloud, since it doesn’t require operating on a separate port, simply goes around the proxy.
Everything else falls into the catchall, which redirects the user to Plex.

#redirect everything to SSL
<VirtualHost *:80>
        RewriteEngine On
        RewriteCond %{HTTPS} off
        RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

<VirtualHost *:443>

        #SSL configuration
        SSLEngine on
        SSLCertificateFile /etc/ssl/certs/server.crt
        SSLCertificateKeyFile /etc/ssl/private/server.key
        SSLCertificateChainFile /etc/ssl/certs/intermediate.crt
        #begin the proxying
        ProxyRequests Off
        ProxyPreserveHost On

        #let owncloud pass straight through
        ProxyPass /owncloud !

        #syncthing doesn't work without a trailing slash in browser URL
        RewriteRule ^/syncthing$ /syncthing/ [R]
        ProxyPass /syncthing/
        ProxyPassReverse /syncthing/

        #default go to plex
        ProxyPass /
        ProxyPassReverse /

        RewriteEngine on
        RewriteCond %{REQUEST_URI} !^/web
        RewriteCond %{HTTP:X-Plex-Device} ^$
        RewriteRule ^/$ /web/$1 [R,L]
