7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.1 DOM Cookie Interface | The cookie attribute of the document (see clause 8.11.4.5.2 "DVBHTMLDocument Interface") provides an interface to the set of attribute-value pairs described in RFC 2109 [43]. The cookie attribute of document is a read/write string with the following behaviour: a) The attribute may be assigned a string value set-cookie ... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.2 Cookie Storage and Lifetime | |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.2.1 Cookie Storage Limits | An implementation should attempt to meet the minimum implementation limits of RFC 2109 [43] including (although not necessarily simultaneously) at least 20 cookies of 4 096 bytes. The size is the total required for the cookies and all attributes stored as strings. |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.2.2 Cookie Persistence | If the application requests permission for access to persistent storage, this is granted and persistent storage is available, an implementation should attempt to store cookies until they expire. If the application does not have permission for persistent storage or the storage is not available then cookies shall persist... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.2.3 Privacy Considerations | Notwithstanding any other requirements in this clause, an implementation may provide mechanisms for controlling the extent of cookie support, including which, if any, cookies are stored, temporarily or persistently. |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.3 Cookie Scoping | |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.3.1 General Rules | All cookies are scoped by dvb-scope. The dvb-scope limits cookies to being accessible by pages in applications of a particular organization (dvb-scope=Org), by pages with a particular Application Identifier (dvb-scope=App) or by pages within all applications (dvb-scope=All). When not specified, the dvb-scope defaults t... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.3.2 Documents delivered via DSM-CC Object Carousel | Cookies set via the DOM on pages delivered by DSM-CC carousel transport are never sent back to a server, even when http: URLs are within the application boundary. The domain, path and secure attributes are ignored for such cookies. |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.3.3 Documents delivered via HTTP transport | Cookies associated with pages delivered by http: shall be scoped by domain and path in addition to scoping by their dvb-scope. If the domain is specified, the cookie is only accessible to pages delivered from hosts within that domain. The default domain is the host name of the http server which delivered the page. If t... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.4 HTTP Cookie Support | |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.4.1 Background | The MHP profile of HTTP 1.0 profile allows both HTTP 1.0 and HTTP 1.1 transport (see clause 6.3.7.2, "MHP profile of HTTP 1.0"). In order for cookie transport to work with existing HTTP 1.0 servers, support for "Netscape" cookie receipt is required. Cookie transmission can always be done with RFC 2109 [43] format since... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.4.2 Sending Cookies | The client shall send cookies per RFC 2109 [43] and for compatibility with older servers, DVB-HTML implementations should use semi-colons to separate cookies rather than commas (both are allowed by RFC 2109 [43]). Only cookies in the scope of the document, including any dvb-scope restrictions, are sent. The client shal... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.12.4.3 Receiving Cookies | The client shall accept cookies via a Set-Cookie header in the HTTP response. The format of the contents of that header may be either in RFC 2109 [43] format or in "Netscape" cookie format, where Netscape format is that specified by the set-cookie BNF from the DOM description above. |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.13 HTTP User Agent String Support | Requests from the DVB-HTML user agent shall include an HTTP header of the form: User-Agent: <user-agent> where <user-agent> is the DVB-HTML user agent string. ETSI ETSI TS 102 727 V1.1.1 (2010-01) 120 |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.13.1 User agent strings | |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.13.1.1 Current user agent-related strings | Current examples (from the internet) of the user agent string are shown in table 60. Table 60: Internet user agent string examples Field Netscape Navigator Internet Explorer on Win2K userAgent Mozilla/4.7 [en] (WinNT; U) Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) appCodeName Mozilla Mozilla appVersion 4.7 [en]... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.13.1.2 User agent string BNF | Adopting "Mozilla" as the appCodeName provides no interoperability benefit, and in fact would be incorrect as the DVB HTML user agent is not required to be Mozilla compliant. In general, the user agent string is best kept short, since it is sent with every HTTP request, hence it is reasonable to use abbreviations where... |

In DVB-HTML additional mechanisms that keep track of the origin of strings in the system and disallow the poten... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.14.2.2.1 Propagation of Internal (safe) vs. External (unsafe) strings | This approach to providing security for the use of ECMAScript maintains application compatibility by distinguishing between value of an internal string type, a string value coming from within the ECMAScript language or literal strings within the application, and an external string type, a string value coming from (susp... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.14.2.2.2 Modifying ECMA-262 to support Internal and External strings | This clause normatively specifies modifications to ECMA-262 [33] to differentiate the two kinds of string values. The present document uses the editing convention that additions to ECMA-262 [33] are given in italics. Text that is removed is presented as strike-out. When a change is made, the old text is given as strike... |

An attempt to use an internal string or a String Object containing an internal string in a runtime code extension shall ... |
7b7f70c9376325894becb0e57e5b31ab | 102 727 | 8.14.2.5 Mutation of Host Objects | Any attempt to remove or replace the pre-defined properties of a host object shall cause the DVBException with the error code SECURITY_VIOLATION_ERR to be raised. Any attempt to remove or replace the pre-defined function property of a host object shall cause the DVBException with the error code SECURITY_VIOLATION_ERR t... |
