+Subject: [PATCH] (#18781) Be more tolerant of old clients in WEBrick server
+
+In #18781 and #6117 there are cases of relatively simplistic puppet
+setups failing between old versions of the puppet client (which
+always use HTTP GET) and new versions of the puppet WEBrick server
+(which has a relatively low limit on the size of a valid GET: 2083
+bytes).
+
+While there are other non-WEBrick server options available, WEBrick
+has the advantage of simplicity, so it would be nice to keep it working.
+
+Here we patch the WEBrick constant which specifies the maximum size of
+a HTTP GET request, increasing it to a value that should work for common
+setups.
