Suddenly aspnet_wp.exe memory builds up

A site we are moving from asp to asp.net has a weird problem. During slow
times it's fine and performs great, however when each server gets about 50
to 60 requests/sec, performance is still great but out of the blue the
memory usage goes from 200-300 mb aspnet_wp and keeps going until the
process gets recycled, it is then fine for a short while. We have made sure
there aren't any large datatables loading or any other sort of data that
could be building up. We also set the sql server to stop any with a cost
over 10 seconds for any connections coming from application. We can not
mimic this in our development environment, it only exists on our web farm of
three servers and it happens on all three servers sporadically. We can not
pin point it to any operation or page. However we are using a few COM
objects that have not been recoded in .NET yet such as jpeg manipulation and
encryption. Does anyone have any ideas how to pinpoint the problem, any ways
to determine what object or code is the culprit. This is still unnoticed by
our customers due to the sql state + load balancer and web farm.. but it
gets very expensive on the processors during busy times to have the
aspnet_wp restart as often as 10 minutes or so during heavy load times.

-Billare you disposing the unmanaged objects properly? a lot of the times, this
is the culprit. see about that first then have a look at the memory profiler
available from the framework to trace this issue. here is a link for further
troubleshooting

Suppressing the URL in a asp.net app

Hi,

I've seen many Internet sites that suppress the URL or show the same URL all
the time your moving around different pages. You'll only see the real page
with it's path in the statusbar way down on the page.

How is that done in asp.net?

I have an example on this, in sweden, stockholm where I live we have a
wellknown kindergarten for older men (warehouse shop) named Clas Ohlson

http://www.clasohlson.se/

You'll also have them on a flaglink in finnish, norwegian and english
language just above the statusbar. So that you see what I mean.

Any ideas?

TIA

Kenneth PThe above link (http://www.clasohlson.se/) is using a frameset. The
address bar isn't updated since you're navigating within a frame of the
page frameset.

Since HTML Framesets are a client side technology, this approach would
work the exact same in ASP.NET.

More info on frames here:

Hi

They are using frames. Just look at the main page "View -> Sourece" and you
will see that page have some frame.
With right click on page you'll see that page has url. Click on top and also
on bottom to see that the page url is different.
Also take a look on frame stuff to undestand clearly what is happening.
There is no trick made in asp.net in that page.

Cheers.

That has nothing to do with asp.net or any other server-side technology,
it is client-side html.
The trick is to use a frameset as your first page. The URL shown is the url of that
frameset definition, the rest of the site works within that frameset.

For that site: use "View | Source" from the menu and scroll down to below the
<NOSCRIPT> section. (strange, a noscript section with embedded javascript...)

Hi jongalloway,

Hmmm...

Have you seen the same technology on pages without frames?

SWF one over another

Hi,
I have got 2 swfs overlain on onto another. This is because I have
skyscraper (displaying jpg, gif or swf) which is moving during scrolling
page. Unfortunatelly there are several swf buttons on the "route" of
skyscraper so sometimes button swfs are on the front instead of being
covered by the skyscraper. I read about parameter wmode and values
transparent, opacity and so on (<param name="wmode" value="opaque" /> or
value="transparent") but it works only for IE not for FireFox.
Bst Regards

You should really ask a Flash forum about this. Asking a Flash question
in a Microsoft newsgroup is probably going to fail :-)
