How do we increase the maximum allowed HTTP GET query length in Jetty

jettysolr

We are using Jetty to run an Apache Solr index. We've had some queries that have grown way beyond the previously expected maximum length, and are now having issues where most queries are not returning any data because the server doesn't respond (browser says "Connection reset").

These requests are not being made through a browser, they're being made programmatically using the Apache_Solr_Service PHP library. The application is expecting queries to come in as HTTP GET requests, so simply switching to a POST will not solve this problem.

How can we increase the maximum allowed HTTP GET query length in Jetty?

Thanks!

How to configure Jetty (via jettyrunner) so that it names a character set in the Content-Type response header

This isn't necessarily a Jetty/Jetty Runner issue. Jetty is the Servlet container, while the response is generated by the servlet (or something higher up which ultimately implements a servlet). Without knowing what you are using above Jetty to generate your content, it is hard to say.

One thing you can do is explicitly define your char-set in the HTML itself using meta tags. HTML5 has simplified how to do this:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Example document</title>
  </head>
  <body>
    <p>Example paragraph</p>
  </body>
</html>

As opposed to the previous HTML syntax:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Example document</title>
  </head>
  <body>
    <p>Example paragraph</p>
  </body>
</html>

How to have Jetty redirect http to https

Speaking for Jetty 9... Here's how you can do it provided that your SSL connector already works:

Step 1: Make sure everything goes through SSL by adding this to your web.xml. If you try to access a resource through HTTP, this will return a 403 !SECURE error

<security-constraint>
  <web-resource-collection>
   <web-resource-name>Everything</web-resource-name>
   <url-pattern>/*</url-pattern>
  </web-resource-collection>
  <user-data-constraint>
   <transport-guarantee>CONFIDENTIAL</transport-guarantee>
  </user-data-constraint>
</security-constraint>

Step 2: Have Jetty redirect to HTTPS when it sees a 403 !SECURE error by adding this to your jetty.xml

<New id="tlsHttpConfig" class="org.eclipse.jetty.server.HttpConfiguration">
   <Arg>
      <New id="httpConfig" class="org.eclipse.jetty.server.HttpConfiguration">
         <!-- This says... Redirect to https://host:8443 if server returns "NOT SECURE" error -->
         <Set name="secureScheme">https</Set>
         <Set name="securePort">8443</Set>
      </New>
   </Arg>
   <Call name="addCustomizer">
      <Arg>
         <New class="org.eclipse.jetty.server.SecureRequestCustomizer" />
      </Arg>
   </Call>
</New>

<!-- This is your HTTP connector, you should have another one for HTTPS -->
<New class="org.eclipse.jetty.server.ServerConnector">
   <Arg name="server">
      <Ref refid="MyServer" />
   </Arg>
   <Arg name="factories">
      <Array type="org.eclipse.jetty.server.ConnectionFactory">
         <Item>
            <New class="org.eclipse.jetty.server.HttpConnectionFactory">
               <Arg name="config">
                  <!-- defined above -->
                  <Ref refid="tlsHttpConfig" />
               </Arg>
            </New>
         </Item>
      </Array>
   </Arg>
   <Set name="host">localhost</Set>
   <Set name="port">8080</Set>
</New>
