I am hoping to get some ideas on how to handle a case when an
application gets too many requests for an application... I would like
to handle the case well...
(1) is the answer in using the queue limit attributes in the config
files and setting the too busy error page (in IIS i think) to nice
error page?
(2) is the answer to create a upfront request-handling application
that doesnt hit the database that counts requests for a certain time
period and sends the user to the application if it is under that
request limit?
(3) what would be nice is .. is to have the user try to hit an
application and if the server is too busy have a nice/clean message
saying the server is busy please wait while we try your request
again...
(3a) but then the question is... what happens if the user hits
refresh over and over...
(3b) this also doesnt but the user in a queue.. and may let another
person jump in line ahead
Thanks in advance...

i run realtime statistical analysis, and report to the user if over
thresholds. for example if the system is > 90% capacity warn the user that
the system may be slow. if > 100%, block at the entry/home page and any
expensive pages.

Hi Ryan,
You probably already thought of this, but just in case, would it not be
better to upgrade your server to a multiprocessor or a web farm rather than
inconvenience the user?
Even if you find a coding solution it would probably only be temporary as
the site will probably get busier.

Thank you for your reply... I believe I was looking for some more
information... and possibly a different approach... but... you might
tell me more about it... do you have a asp.net app that reads these
requests and gives back information to the user if over a threshold?
I'll try to search on the name you have given me in the meantime...
An example of what i am trying to do: I have an online sales website
which may have a lot of users hitting it at a certain time... whats
the best way to handle this?
could someone reply to the points I have in 1ST message above?
------------
ALSO I am sorry for the grammatical errors in the first message..
This is a rare case senerio... and should not happen but yearly.
I am leaning toward the following approach... however I would still
like to hear what people have to say...
---------------------------
(1) i will set the queue limit attributes in the process model
element... so dot-net redirects to a 503 error if too busy...
(2) then I will show a custom 503 errorpage..
.... would that not be a good approach?

Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

I need a HTTP server handling long lasting requests e.g. 10-30 seconds.
Below is a pice of the code. In order to make the server reponsive while
handling othere requests I use SocketServer.ThreadingMixIn.
However the problem is the it does not work out. I checked thet a new
thread is created for each new connection new, but the main loop seems
to be frozen until the prevoius handling ends.
What could go wrong?

Hello,
I have an application that processes thousands of files each day. The
filenames and various related file information is retrieved, related
filenames are associate and placed in a linked list within a single object,
which is then placed on a stack(This cuts down thread creation and deletions
roughly by a factor of 4). I create up to 12 threads, which then process a
single object off of the stack. I use a loop with a boolean...

Hi all
I have an automated application, that runs in the middle of the night.
If certain 'non system' errors occur (things like malformed files, missing
files etc..), I send an automatic Email and write a record to the database.
This is handled in a class.
When these errors occur, once Emailed and written I want to just end the
App, simple as that.

Hi,
I am writing a Win32 DLL. I want to be able to handle any SEGVs
(segmentation violations) gracefully, by using an error handler of sorts.
Currently, if a user of my DLL (typically a VB programmer) passes a null

leaving shared memory, database connections etc in a "dirty" state. I
would like a way of gracefully handling user "actions" like this -

Hi, all.
Need help with what seems to be either connection, or threading problem in

The gist of the problem is this: IHttpHandler in my application serves an
HTML page that has two images (image A and image B) in it. Once the HTML page
is served, expected behavior is this:
1) receive request for image A,
2) receive request for image B almost at the same time as for A,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
