In the study and use of ASP, response object involved in a lot of aspects, want to master also is not a day or two, I was also recently found that response object has such a property, on the ASP in some large resource page, there is a certain "optimization" effect, That's the isclientconnected attribute.
This property can be used at the time the ASP runs to determine whether the service end is disconnected from the polite end and returns True or false. This also prevents a user from accessing a resource-intensive page because the server-side program continues to execute when the user refreshes or closes the page, which results in no immediate release of the resource.
isclientconnected Related Instructions
The IsClientConnected property is read-only, indicating whether the client is connected to the server since the last call to Response.Write.
Grammar
Response.IsClientConnected ()
Notes
This property allows the user to have more control when the client is not connected to the server. For example, when a request is made from a client and the server responds with a lengthy period of time, this may help ensure that the client is still connected until the script continues.
Sample
The following is a reference fragment:
<%
' Check to ' if the ' client is connected
If response.isclientconnected Then
Response.Flush
Else
Response. End
End If
%> |
