Hi All
I had an interesting situation today where I discovered that the 4D
Web Server 'Inactive Web Process Timeout' setting (Preferences -> Web
-> Advanced) has no effect on 4D Client unless you activate the 'Re-
Use Temporary Context' checkbox (Preferences -> Web -> Configuration -
> Starting Mode). This checkbox doesn't seem to appear in 4D Single
user - only 4D Client. (4D 2004.5).
When I activated this I observed a VERY substantial performance
improvement - specially on image loading, which is handled by a
separate server. I discovered the timeout wasn't working (or was
effectively set to zero seconds) after I noticed the 4D Server (Data
server) console activity monitor oscillating wildly, and on expanding
the client connection line, could see the web processes birthing and
dying for every single page request.
HOWEVER, PROBLEM: When I activate this mode, everything seems to
behave normally, except a script containing the following Active4D
function . . .
$P_SECURE:=num(get request info("*secure"))
. . . seems to return 0 (zero) instead of 1 for a secure page request.
I'm not sure if this is because 4D has problem in re-using a process
which previously handled an non-secure request for handling a secure
one, or if it's to do with the request header being cached in an
obscure process variable somewhere, or if it's something to do with
Active4D.
Anybody got any ideas ?
Regards
Peter
