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

Question

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!

<Set name="headerBufferSize">65536</Set>

is now deprecated. You can use:

<Set name="requestHeaderSize">65535</Set>

instead.

I am using Solr 4, and using 65536 prevented the instance from starting. Using 65535 worked. – Redtopia May 13 '15 at 21:56
I wasn't sure where to put the config setting. For me it was under `dist/server/etc/jetty.xml`. – Tyler Collier Jul 10 '20 at 15:10

A little late to the party, but I've just come up against the same problem.

Add the following to the connectors section of jetty.xml:

<Set name="headerBufferSize">65536</Set>

This will increase the header limit from the default of 4KB to 64KB.

This solution worked for us. The symptom in the logs was `java.io.IOException: FULL`. Make sure to add the setting in whichever active `addConnector` section you're using. – Tom Harrison Jr Dec 12 '13 at 20:20

Thanks but I said Jetty, not Tomcat. I can't seem to find anywhere in Jetty's configuration files where I would put the settings you've linked to. – Michael Moussa Apr 27 '10 at 15:12

Tried it. No luck. – Michael Moussa Apr 28 '10 at 12:44
We decided to ditch Jetty and switch to Tomcat. After doing so, we were able to make the changes indicated in link you provided and are no longer experiencing problems. Thanks! – Michael Moussa May 05 '10 at 17:08

To increase the limit on the request header size at Solr side. if you are running Solr on Jetty, perform the following steps:

Open the \server\etc\jetty.xml file. Change to

Save the changes.
Restart Solr and Sitecore XP.
