|Currently no. HTTP is connectionless, and that makes it hard to
|do things after a transaction is completed.
Except perform another transaction :)
The problem is that the data change on the server side and there is no
way in the current HTTP model for the server to contact a client to
inform them of this.
A solution that would be within the http model would be for the server to
inform the client that the content of this document changes rapidly and a
interval for refreshed. Something like:
C: GET /stock_quote.html HTTP/1.1
S: HTTP/1.1 200 OK
Content-type: text/html
-->Refresh: <time_interval>
Last-modified: Wednesday, 07-Dec-94 22:03:38 GMT
Expires: Wednesday, 07-Dec-94 22:03:39 GMT
Content-length: 1721
This would allow the client to set a timer and perform a GET on the URL
every time_interval so you would have the perception of a dynamically
updated document. The updates would be dependent on the alarm clock, of
course, instead of any real change in the content of the document, but I
think its the closest you are going to get under the current scheme.
