Hi,

I have set "Keep-Alive" in the TidHTTPServer. This keeps the sockets open.

Is there any timeout for this connection, or a max number of requestes that 
will be served for each connection?

Or do I need to program this myself?

The reason why I am asking is that Apache implements this and I would like 
to implement the same behavior. For Apache documentation:
KeepAlive
Syntax: KeepAlive max-requests
Default: KeepAlive 5

This directive enables Keep-Alive support. Set max-requests to the maximum 
number of requests you want Apache to entertain per connection. A limit is 
imposed to prevent a client from hogging your server resources. Set this to 
0 to disable support.

KeepAliveTimeout
Syntax: KeepAliveTimeout seconds
Default: KeepAliveTimeout 15

The number of seconds Apache will wait for a subsequent request before 
closing the connection. Once a request has been received, the timeout value 
specified by the Timeout directive applies.

I will re-post this in the delphi forum as well - where it should be posted 
in the first place.

Sorry about that.

There are two timeouts that are available which you can use to manually 
mimic the functionality you are asking for (there is no timeout specific for 
it):

1) the connection's ReadTimeout property.  If the client does not send a new 
request during the specified interval, the connection will timeout and 
disconnect.  But it will also timeout if the connection is slower than the 
interval as well.

2) the server's SessionTimeOut property.  If the client does not send a new 
request using an existing session during the specified interval, the session 
will timeout.  You can use the OnCreateSession event to associate a 
connection with a session, and then use the OnSessionEnd event to disconnect 
the connection.

No.

Yes.
