Comments, Comments, Read all about it...

Hmm... unlike other blog software that I have used, this blog does not give you the ability to send anonymous email via a form from the blog to me.

So, I will try to simulate such functionality by dedicating this blog entry's comment section towards allowing you to send anonymous email to me. I hope that the CAPTCHA requirement on comments will limit anonymous blog comment spam that I have seen in the past.

Yes... yours and my email addresses remain private, but the comment contents are no longer private. That should be ok for the most part because my answers to your questions will be publicly posted anyway...

Plus, you get to see all of what have been asked before... and maybe find that you no longer need to comment...

But, if you truly need to send a private email to me, that can be separately arranged. :-)

Cheers!

//David

David, I'm certainly not privy to the politics or (mis?)management over at MS, but I for one am glad to see that you're continuing to blog.

The funny thing is that I know I've given positive feedback specifically about the value of developer's blogs like yours, so its a bit disheartening to hear that the management seems to disagree, or at least censor what you guys feel inclined to share.

Hang in there, keep blogging, and good luck with whatever team you are on now.

A have a Windows 2003 SP1 R2 server running IIS6.0 and SQL Server 2005 SP1 with intranet application written on ASP some self-made DLL. Previously our site run on another server Win2003 sp1 IIS6.0 SQL 2000 sp3.

Intermittently the IIS server stops processing ASP requests (during this time
it continues to serve html pages). The CPU and memory useage appear normal.
The server will rectify itself after a period of 2 to 5 minutues, but some time hang forever.
What i tried:
1) Disable any extension except ASP and SSI, remove all isapi filters from "default web site" and "web sites".
2) PoolMon:

3) Copy all IIS setting from old server - by visual compare IIS manager's screes.
4) IISState :)
5) perfmon

Now symptoms are:
At random server freeze ASP processing, browser simply go in a wait state. Perfmon show that "Web Server - Current ISAPI extension request" start to grow from 0/1 to 10-40. At one time "web server - current connection" (?10-20 at normal), "asp - request execution" (0-2), "asp - request queued" and "asp - request execution time" (0) grow up. Memory for w3wp.exe also growing from 50mb to 150mb and higher.
Then a number of Current ISAPI request stop to grow, and after a pause IIS self-recover. At that moment all counter drop back to zero, and in httperror appear entries "Connection_dropped DefaultAppPool".

IISState analyze log (dump is taken at hung time):

Hi David,

Great to see you are still blogging in a Q&A style, I know it is greatly appreciated by anyone who has entered the murky world of ISAPI. On to my question:

I realize this is a little application specific but I also know the FPRPC code is owned by the IIS team even though they hardly ever admit it.

I have an ISAPI filter and I am trying to replace the document data returned in an FPRPC Get Document method (DoSendRawData). I am leaving the headers and the FP metadata html block untouched.

When I trace the client receipt it all looks correct however the FPRPC client (Microsoft Word 2007 in this case) does not seem to like the response and kicks out to some OPTIONS calls and then a straight GET on the doc url (which I don't want).

Is there any cross-check between the headers, metadata and content of the response? Is there any integrity check across methods (for example the docs_meta_info method)? Lastly, do you know of any documentation on what the rsponse of a Get Document call should return?

Also, any (and I mean any) nugget of wisdom on FPRPC would be gratefully appreciated.

Many Thanks,

Brian

David ... I needing all the assistance I can get on the following problem ...

abridged version:

we use ISA server 2004 as a proxy. In conjunction, on same server we have SurfControl...which is a "plug-in" for ISA. Surfcontrol scans all user web traffic, and blocks traffic to inappropriate web sites.

ISA server seems to have a single radio button which specifies "require authentication"...it is seemingly an all-or-none proposition.

If I do not check "require authentication"...then the audit logs within ISA and Surfcontrol do not contain client machine name, nor client username. The audit records will only contain client IP address...which is virtually useless looking at historical logs (when you want to know what web sites Billy-Bob hit over the last 6 months). Regularly, the HR department will request such info....what sites has Billy-Bob been browsing for the last 6 months. These are usually employee discipline, preparing to "fire" Billy-Bob situations.

If I check "require authentication"...then the audit logs tell me username. KEWL!

Whoops....half of our client base are off site sales folks who never logs on to the network, but rather use cached credentials to the local machine and then use VPN to get on the network. Double-whoops -- if I have checked "require authentication"....ISA server says to these users -- "I don't know who you are...here is your username/password prompt...so you can browse the internet". Double-damn.

Do not want username/password prompt for users to surf internet -- so I remove "require authentication" requirement...and my audit logs are worthless.

So I checked out a sample webfilter program for ISA called MyAuth http://msdn2.microsoft.com/en-us/library/aa503245.aspx

It is a C++ .net application. I am able to install the program using .net on the ISA server ... register the myauthfilter.dll. It prompts the user for a user name (no password) and then uses that username as "authentication". It appends the username (name=username) to the end of the URL which messes up some web pages.

I would like to pick up a piece of info from the PC like computername and feed it as authentication (since the myauth, really does not autheniticate it only takes info and uses it) to MyAuth to give it useful info for the ISA log file and not prompt the user for anything... sound reasonable?

But I am lost with C++ and all the APIs available.

Maybe I am taking a bad path ... if the user's where truely authenticated to the network I would not have this problem. Is there a way to force authentication after the user has authenticated locally using cached creditials?

Any leads / thoughts? Please I am despirate.

Packets in DoSendRawData:

I would like to redirect in an ISAPI filter by replacing the first packet with a 302 status. However I can only decide upon whether to redirect or not based on subsequent response packets. I can save off the first packet and the let it through or replace after I have got the next packet but I would prefer not to get into that because I could potentially mess up requests I'm not concerned with.

Is there any built-in ISAPI support for "holding back" packets?

Hi David, we traded some posts in microsoft.public.inetserver.iis -- I hope it's ok to try you here.

(fwiw, I'm scott AT turnstyle.com)

I have a new/clean Vista install with just:

1) a few hardware drivers

2) IIS (with ISAPI & CGI enabled)

3) Windows Update patches

4) PHP 5.2.5 -- I unzip PHP into inetpub and map *.php to PHP5isapi.dll

I can open a PHP page, but if I then go to IIS Manager and refresh the default application pool, I get a "Worker Process has stopped working" alert and a crash in Event Viewer.

I don't know what more to try -- I wonder whether others are having the same problem? (ie, can this even be fixed, or is it something to "get used to"?)

Many Thanks for any suggestions! -Scott

David, could you look into posting an article outlining how to run nested ASP.NET applications? Specifically, there is a lot of confusion on how you can merge multiple web.config files that are used by various applications. For example, I use BlogEngine.Net and would like to have ScrewTurn wiki running in a subfolder. I have yet to find good documentation on how best to work through the problems of merging the two web.config files in order to make everything work correctly. You seem like the right person to help resolve this issue.

In a blog on ISAPI extensions lifetimes, you mention this:

'As for safety - it is safe to spawn your own threads from within an ISAPI Extension - for example, ISAPI Extension using a Thread Pool to queue/process requests asynchronously does this, by design. What you need to ensure is that if those threads touch the ECB (or any other memory, for that matter), that the ECB is valid. For synchronous request, the ECB will not be valid in between HttpExtensionProc calls (its lifetime is tied to the HttpExtensionProc lifetime for that particular request). For asynchronous requests, ECB will stay valid until HSE_REQ_DONE_WITH_SESSION is called on that ECB.'

I'm confused here about the 'or any other memory' phrase. Do you mean that the thread may never touch any memory when out of the HttpExtensionProc context? That would render any background thread a bit useless (unless it's ok to alays return a pending status). I don't really see why memory allocated by the DLL itself can't be touched.

Regards,

Ton

Hi, David,
I have a different question -
it would be great if you could elaborate on the following (your post):
THANKS!!

You will not be able to use Client Certificates with a Load balancer
that serves as the SSL termination point.

You will have to choose whether Load balancing or Client Certificates
based security is more important because by their very natures, they
are incompatible. Client Certificate cannot be re-transmitted once it
has been terminated, which is necessary for their security (if Client
Certificate could be retransmitted, then how can the recipient be sure
that the sender is the actual sender and not an imposter who
retransmits a forgery? This uncertainly undermines the point of Client
Certificate proving identification). Load balancing is going to
terminate the request so that it can balancing amongst its internal
pool of servers. The two won't mix.

It seems like you are saying that Client Certificates are more
important since you are willing to allow traffic to bypass Load
balancer, in which case the individual server must have a certificate
whose name matches what the external user typed (either exact or via
wildcard certificate). i.e. treat it like any other SSL server you
directly expose.
