</P><P>The user’s client can store an avatar in the user vCard.
|
||||
The vCard-Based Avatars protocol (<A HREF="http://xmpp.org/extensions/xep-0153.html">XEP-0153</A>)
|
||||
provides a method for clients to inform the contacts what is the avatar hash value.
|
||||
However, simple or small clients may not implement that protocol.</P><P>If this module is enabled, all the outgoing client presence stanzas get automatically
|
||||
the avatar hash on behalf of the client.
|
||||
So, the contacts receive the presence stanzas with the Update Data described
|
||||
in <A HREF="http://xmpp.org/extensions/xep-0153.html">XEP-0153</A> as if the client would had inserted it itself.
|
||||
If the client had already included such element in the presence stanza,
|
||||
it is replaced with the element generated by ejabberd.</P><P>By enabling this module, each vCard modification produces a hash recalculation,
|
||||
and each presence sent by a client produces hash retrieval and a
|
||||
presence stanza rewrite.
|
||||
For this reason, enabling this module will introduce a computational overhead
|
||||
in servers with clients that change frequently their presence.</P><P> <A NAME="modversion"></A> </P><!--TOC subsection <TT>mod_version</TT>-->

|
||||
|
||||
The user's client can store an avatar in the user vCard.
|
||||
The vCard-Based Avatars protocol (\xepref{0153})
|
||||
provides a method for clients to inform the contacts what is the avatar hash value.
|
||||
However, simple or small clients may not implement that protocol.
|
||||
|
||||
If this module is enabled, all the outgoing client presence stanzas get automatically
|
||||
the avatar hash on behalf of the client.
|
||||
So, the contacts receive the presence stanzas with the Update Data described
|
||||
in \xepref{0153} as if the client would had inserted it itself.
|
||||
If the client had already included such element in the presence stanza,
|
||||
it is replaced with the element generated by ejabberd.
|
||||
|
||||
By enabling this module, each vCard modification produces a hash recalculation,
|
||||
and each presence sent by a client produces hash retrieval and a
|
||||
presence stanza rewrite.
|
||||
For this reason, enabling this module will introduce a computational overhead
|
||||
in servers with clients that change frequently their presence.
