Portlet Response headers

The portlet response headers are part of the portal Configuration Service.

    portletcontainer.response.headers.additionallyNotAllowed = <none>
    There is a predefined set of response header fields we cannot use in portlet response fields. These unallowable header fields are listed later in this topic. In addition to these predefined header fields we can define additional fields that are then also not allowed to be included into a portlet response header. If we specify more than one field, we must separate the values by commas.

    portletcontainer.response.headers.forceAllowed = (none)
    This property enables us to re-enable the usage of the header fields that are by default prohibited header fields. If we specify more than one field, we must separate the values by commas.

The following list shows the header fields of the HTTP 1.1 (RFC 2616) specification that are by default not allowed to be set:

    6.2 Response Header Fields:

    The response-header fields allow the server to pass additional information about the response that cannot be placed in the Status-Line. These header fields give information about the server and about further access to the resource identified by the Request-URI.

    • Accept-Ranges (Section 14.5)

    • Location (Section 14.30)

    • Proxy-Authenticate (Section 14.33)

    • Server (Section 14.38)

    • Vary (Section 14.44)

    • WWW-Authenticate (Section 14.47)

    7.1 Entity Header Fields:

    Entity-header fields define meta information about the entity-body or, if no body is present, about the resource identified by the request. Some of this meta information is optional; some might be required by portions of this specification.

    • Allow (Section 14.7)

    • Content-Encoding (Section 14.11)

    • Content-Language (Section 14.12)

    • Content-Length (Section 14.13)

    • Content-Location (Section 14.14)

    • Content-MD5 (Section 14.15)

    • Content-Range (Section 14.16)

    • Content-Type (Section 14.17)

    • Expires (Section 14.21)

    • Last-Modified (Section 14.29)

    4.2 Message Headers:

    HTTP header fields, which include general-header (section 4.5), request-header (section 5.3), response-header (section 6.2), and entity-header (section 7.1) fields, follow the same generic format as that given in Section 3.1 of RFC 822 [9]. Each header field consists of a name followed by a colon ( : ) and the field value. Field names are case-insensitive.
