If specified, then the correlation ID used in the HTTP response will be derived from this set of request headers. These headers will be checked in the order listed in the configuration, and the first header found in the request will be used. If no header from this set is found in the request, or if this property is not defined, then a new correlation ID will be generated by the server. This property is ignored if the use-correlation-id-header property is not enabled. |
| Default Value | If no source headers are specified, then the correlation ID will always be generated by the server. |

| Default Value | 128 |
| Allowed Values | An integer value. Lower limit is 1. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |

idle-time-limit (Advanced Property)
| Description | Specifies the maximum idle time for a connection. The max idle time is applied when waiting for a new request to be received on a connection, when reading the headers and content of a request, or when writing the headers and content of a response. |
| Default Value | 200 seconds |
| Allowed Values | A duration. Lower limit is 1 milliseconds. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
low-resources-connection-threshold (Advanced Property)
| Description | Specifies the number of connections, which if exceeded, places this handler in a low resource state where a different idle time limit is applied on the connections. A value of zero indicates that the server will enforce the low resource idle time limit automatically whenever there are not enough request handlers allocated to handle the current load. |
| Default Value | 0 |
| Allowed Values | An integer value. Lower limit is 0. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |

The max idle time is applied when waiting for a new request to be received on a connection, when reading the headers and content of a request, or when writing the headers and content of a response. |
| Default Value | 200 seconds |
| Allowed Values | A duration. Lower limit is 1 milliseconds. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
enable-multipart-mime-parameters (Advanced Property)
| Description | Determines whether request form parameters submitted in multipart/ form-data (RFC 2388) format should be processed as request parameters. Most web applications use the "application/x-url-encoded" method to submit form parameters in a compact format, e.g. param1=value1¶m2=value2. There is no opportunity to apply differing charsets, content-types or transfer-encodings as described in RFC 2388. Enabling multipart-mime form parameter processing allows the form parameters above to be expressed as named parts with greater content control in HTTP servlet extensions. Form processing in web application extensions is unaffected. This is an example of a multipart/form entity: Content-Type: multipart/form-data; boundary=separator --separator content-disposition: form-data; name="param1" content-type: text/plain;charset=utf-8 content-transfer-encoding: 8bit value1 --separator content-disposition: form-data; name="param2" content-type: text/plain;charset=windows-1250 content-transfer-encoding: quoted-printable value2 --separator-- |

| Admin Action Required | The HTTP Connection Handler must be disabled and re-enabled for changes to this setting to take effect. In order for this modification to take effect, the component must be restarted, either by disabling and re-enabling it, or by restarting the server |
use-forwarded-headers (Advanced Property)
| Description | Indicates whether to use "Forwarded" and "X-Forwarded-*" request headers to override corresponding HTTP request information available during request processing. These headers are usually set by proxies to disclose information about the original request that would otherwise be lost during the proxying process. The information in these headers will be used to update the request information exposed to Logging, Web Application Extensions, and HTTP Servlet Extensions. The following headers are supported:
|
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | The HTTP Connection Handler must be disabled and re-enabled for changes to this setting to take effect. In order for this modification to take effect, the component must be restarted, either by disabling and re-enabling it, or by restarting the server |
http-request-header-size (Advanced Property)
| Description | Specifies the maximum buffer size of an http request including the request uri and all of the request headers. The default value may be increased if the server is required to process unusually large GET requests or if a large amount of client state needs to be maintained via headers. |

This is only applicable if clients are allowed to use SSL. |
| Default Value | disabled |
| Allowed Values | disabled - Clients are not required to provide their own certificates when performing SSL negotiation. optional - Clients are requested to provide their own certificates when performing SSL negotiation, but still accept the connection even if the client does not provide a certificate. required - Clients are required to provide their own certificates when performing SSL negotiation and are refused access if they do not provide a certificate. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | The HTTP Connection Handler must be disabled and re-enabled for changes to this setting to take effect. In order for this modification to take effect, the component must be restarted, either by disabling and re-enabling it, or by restarting the server |
