Missing Doctype HTML Deployment using apache mod_proxy

I have a strange problem...

My Vaadin Application is working fine on my computer (locally). I just deployed the website and now I have a problem:

The <!Doctype html> tag in the first line is missing. I don't know why it is, but I think this is causing some problems, because the Website is being displayed in Quirks mode.

The funny thing is, when I run the application locally, the doctype tag is set.

I simply exported the application to a war file and deployed it.

I haven't found any soloution on the Internet so far...

Is this a Tomcat setting problem or anything else?

Solution

  • Already found the problem!

    I was using Apache mod_proxy to handle my web application. The html doctype was not set in the proxy_html.conf. I simply had to define the ProxyHTMLDocType to HTML 5 in the proxy_html.conf.

    proxy_html.conf:

    ProxyHTMLDocType "<!DOCTYPE html>" // Sets the Doctype to HTML5
