Is there any parameter for HTTP/HTTPS connectors which is equivalent to the maximum packet size for AJP connector in JBoss?

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 5.x
  • 6.x

Issue

• I can configure the max packet size (packetSize) for the AJP connector. But how can I do this for the HTTP connector?

Resolution

• packetSize is only an AJP specific parameter. Since HTTP is not a packet-oriented protocol like AJP, you don't need to worry about packet size and there's no exactly equivalent parameter in HTTP/HTTPS connectors. However, the closest parameter for HTTP/HTTPS connectors would be the max header size, which defaults to 8192.

EAP 6.x

• You can configure the max header size for HTTP/HTTPS connectors by setting the system property org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE. For example:

<system-properties>
    <property name="org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE" value="8192"/>
</system-properties>

• On EAP 6 Domain Mode, you can set it to each individual host:

[domain@192.168.100.1:9999 /] /host=laptopHost/system-property=org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE:add(value=8192)
{
    "outcome" => "success",
    "result" => undefined,
    "server-groups" => undefined
}
[domain@192.168.100.1:9999 /] /host=laptopHost/system-property=org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE:read-resource
{
    "outcome" => "success",
    "result" => {
        "boot-time" => true,
        "value" => 8192
    }
}

Or set it to each server-group:

[domain@192.168.100.1:9999 /] /server-group=production-group/system-property=org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE:add(value=8192)
{
    "outcome" => "success",
    "result" => undefined,
    "server-groups" => undefined
}
[domain@192.168.100.1:9999 /] /server-group=production-group/system-property=org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE:read-resource
{
    "outcome" => "success",
    "result" => {
        "boot-time" => true,
        "value" => 8192
    }
}

EAP 5.x and earlier

• You can configure the max header size by setting the maxHttpHeaderSize attribute on the HTTP/HTTPS connectors in $JBOSS_HOME/server/$PROFILE/deploy/jbossweb.sar/server.xml. For example:

<Connector protocol="org.apache.coyote.http11.Http11Protocol" port="8080" address="${jboss.bind.address}" 
         connectionTimeout="600000" maxHttpHeaderSize="8192" redirectPort="8443" />
