title: Tomcat 7.0.43 "INFO: Error parsing HTTP request header"
body: <p>I use Tomcat 7.0.43 with a websocket application. My app works fine in Tomcat 7.0.42 but with 43 I get the following output when I try to access my server on websockets:</p>
  
  <pre><code>Sep 16, 2013 3:08:34 AM org.apache.coyote.http11.AbstractHttp11Processor process
  INFO: Error parsing HTTP request header
   Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
  </code></pre>
  
  <p>My browser console shows the following: </p>
  
  <pre><code>WebSocket connection to 'ws://www.testapp.com/socket/notification/848df2e62fcf93e1b3?X-Atmosphere-tracking-i…Date=0&amp;Content-Type=application/json;%20charset=UTF-8&amp;X-atmo-protocol=true' failed: Unrecognized frame opcode: 5 
  </code></pre>
  
  <p>Here is the access log for that request: </p>
  
  <pre><code>"GET /socket/notification/848df2e62fcf93e1b3?X-Atmosphere-tracking-id=0&amp;X-Atmosphere-Framework=2.0.2-javascript&amp;X-Atmosphere-Transport=websocket&amp;X-Atmosphere-TrackMessageSize=true&amp;X-Cache-Date=0&amp;Content-Type=application/json;%20charset=UTF-8&amp;X-atmo-protocol=true HTTP/1.1"
