ASP.NET configuration hierarchy (web.config)

Teamsite 6.1 (SP2) / Windows

Hi,

We have an ASP.NET website being content managed by Teamsite. Below the root directory - which is itself an application as per the instructions for virtualising .NET sites in Teamsite - there are 2 further directories which are defined as Applications within IIS. When virtualising in Teamsite these applications are giving errors.

The child applications have their own bin directories and their own web.configs. When deployed to the live server the applications run as expected with the local web.configs inheriting and extending the parent application's web.config settings. In short outside of Teamsite everything works. For ref on what I mean see: http://www.microsoft.com/resources/documentation/iis/6/all/proddocs/en-us/aaconaspnetwebapplicationdeployment.mspx

Within Teamsite the child applications aren't recognising the settings and values defined in the child/local web.configs and only the website's root web.config is functional. I found that if I put the settings into the web.config at the root of the website these child applications work, problem is some of the values need to be different to those in the root web.config so that's not a suitable workaround. I've tried everything and as it seems to be only within the Teamsite environment that I get this issue I wondered if anyone else out there has experienced the same problem or found a solution.

[Note - the machine.config has

<location allowOverride="true">

and I can't see anything else in the root's configuration that would prevent the web.config files in these subdirectories from extending and overriding the parent values]

thanks
Anita

Hi Anita,

I have been working on the same problem ... as best as I can tell the problem appears to be a conflict with the TeamSite ISAPI plugin. In a nutshell, without the ISAPI Filter installed the web.config files are recognized, with it installed, they are ignored and only the root web.config appears to be visible. Of course removing the ISAPI Filter will break any server side includes and/or virtualizations.

Assumming the above is THE problem, you would need to use the proxy mappings in iw.cfg to map specific Workareas to specific IIS websites.

The problem may be either a conflict with the ISAPI filter or with remappings that the filter is doing. The best way to debug this is to add a line:
_debug=yes
to the [iwproxy_plugin_remap] section of iw.cfg and restart IIS ("net stop w3svc" "net start w3svc" or use services panel). This will produce a debug log in c:/temp/iw_isapi.log. Since the log is pretty verbose, it's best to turn it on, do one known request, and then turn it back off. This log will show URLs in various parts of the remap process and what remappings the plugin is making. It may shed some light on the situation. It's also one of the first things support will ask for if you need to open a case for this.

I am having the same problem too.

Did you find a solution? Can you share your solution, if you had been lucky?

Any help would be appreciated.

Thank you

Usha,

I'm sorry to say we haven't found a solution.

We ended up having to workaround it as I'd wasted too much time trying to fix it. We just had to but everything we possibly could in the root web.config and where nested applications require different settings Teamsite will just ignore their web.configs so we've just had to ensure all the error trapping accounts for it to enable virtualisation but then everything's fine when it's deployed to staging or live.

Not even a good workaround really. I didn't get anywhere with remapping.

Likewise if you find a solution, please post it.

Thanks Ani

I have posted this as a support request to Interwoven. Let's see what their response is.

I will share with you if we find a solution.

Hi all,
Has a solution has been found to the APS.NET configuration hierarchy problem? I'm very curious to know the outcome of the support request to interwoven because I'm currently having the same difficulties myself.

Thanks!
