External data in HTML

documents

HTML documents can reference external

files (for example, a GIF or JPEG file for a

graphic).

Not all these external formats are

supported by all Web clients.

When the document contains such data, the

Web client can send a request to the Web

server to provide the relevant graphic.

If the Web client does not support the

format, it does not request the information

from the server.
