ColdFire causing Firefox error

[rbarthle17]

Using the latest ColdFire on Firefox 11.0, if a page has even a medium amount of data in it with CF Admin routing debugging through COldFire, Firefox will throw a "The connection to the server was reset while the page was loading" error. Turning off request level debugging, or switching it to cassic.cfm or dockable.cfm fixes this, so it's something with ColdFire it seems.

OS X Lion 10.7.3 MAMP Pro CF 9.0.1

Is there any update on this issue? Unfortunately I don't use MAMP so I can't test this.

That said, I know some servers have size limits on HTTP headers. Maybe this is the case with something in the MAMP stack?

You need to increase the size limits for the HTTP headers. For the development version of ColdFusion10 using the Tomcat server goto the file ColdFusion10/cfusion/runtime/conf/server.xml. About line 83 you should see something like

<Connector executor="tomcatThreadPool" maxThreads="50" maxHttpHeaderSize="32768" maxHeaderCount="200" port="8500" protocol="org.apache.coyote.http11.Http11Protocol" connectionTimeout="20000" redirectPort="8445" />

You need to add the attributes maxHttpHeaderSize, maxHeaderCount. The default values are 8192 bytes for maxHttppHeaderSize and 100 for maxHeaderCount. I increased mine to 32768 and 200 respectively. The maximum value for maxHttpHeaderSize is 65536. You need to restart the ColdFusion server after changing these values.

Here is my amended Connector setting:

<Connector executor="tomcatThreadPool" maxThreads="50" maxHttpHeaderSize="32768" maxHeaderCount="200" port="8500" protocol="org.apache.coyote.http11.Http11Protocol" connectionTimeout="20000" redirectPort="8445" />
