How to customize "server too busy" error page?

[DC]

Hi,

there is a 500;13 page one can configure in the website properties, but
..Net Framework 1.1 also delivers the "server too busy" message
sometimes and the IIS custom error page does not seem to catch that.

How would I customize the error page then?

Regards

You should be able to map a custom error page in the web config file and
filter by error codes. Unfortunately, depending on when the error occurs,
before it hits the pipeline, it may not be redirected to the error page.

Yes indeed. This is especially the case for "Page cannot be found" errors,
particularly when the page in question isn't an aspx...

Thank you. Is there no way to get a grip on the "server too busy" page
or implement a redirect into that page - no matter where in the
pipeline the error occurs? I mean, is the page hardcoded into a dll?

I understand that a "service unavailable" message may appear if IIS is
simply unable to return anything else, but I cannot understand that I
am forced to possibly return a more complex framework error page
without any options to customze / hide it. That looks really crappy in
a professional application.

Not following you. This can be any page, html or aspx. I don't see the
complexity. If you want to catch IIS you probably need to implement some
sort of script hooked in to IIS - more work than is justifiable.
Respectfully, I suggest digging your head in the sand on this one after
mapping a custom page.

By "more complex page" I was only referring to the fact that the
"server too busy" error page is a typical framework error page, as
opposed to "service unavailable" which is minimal for a cause. I want
to present a lean custom page instead and it looks as if I can't.
Typically one can configure custom error pages like

<configuration>
<system.web>
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly">
<error statusCode="500"
redirect="InternalError.htm"/>
</customErrors>
</system.web>
</configuration>

but it looks like there is no way to customize the "server too busy"
message and I think that's unprofessional. At least I have a hard time
explaining these error pages to my customer.

Oh ok I see what you are saying.
Run inetmgr from a command prompt, navigate to your root website,
right-click and select properties. Under the custom error tab, scroll down
to the 500 HTTP error and double click it. Change it from default to url.
Enter a valid url pointing to a resource that contains a nice error message.
Document that change somewhere please so developers have an idea what is
happening.

I did that, actually the "too busy" error should be a 500;13 error.
Customizing this (and all 500 errors) did not do anything. It looks
like ASP.Net is outputing the error page and IIS is delivering it with
no hesitation (and no error code in the HTTP header).

An additional problem is that I cannot really provoke the 500;13 error
for testing, although there is an approach here:

http://blogs.msdn.com/rahulso/archi..._2200_Server-Too-Busy_2200_-Errors_3F00_.aspx

But that only got me "Service Unavailable" error. I am about to give up
on the topic, we did not see too many "too busy" errors lately. Maybe
the only way is to capture the page with a (hardware) proxy and replace
the Html when there are certain keywords in the page.
