We have an ASP.NET 3.5 application which we are trying to get to work using the Cassini web server. When the application is launched, the login page correctly appears. However, when a correct username and password are entered and the Log In butten is pressed, the following error is generated:


Server Error in '/' Application.

---

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Default.aspx

---

Version Information: Microsoft .NET Framework Version:2.0.50727.4016; ASP.NET Version:2.0.50727.4016



If however I launch the application and at the login page I press another button which takes me directly to another page (recover password) without loging in and then use a menu entry that sends me back to the login page and then enter the very same username and password and press the Log In button, it works fine.

Also, if I launch the application from the Cassinin Web Server Explorer, it works fine.

We are using the ASP.NET authorization mechanism. The startup page is default.aspx and the application is configured to always go to the login page if there is no authorized user. The one exception to this is that as mentioned above, the recover password page can be gone to from the login page without a user being authorized.

The log in page has the following setting:
DestinationPageUrl="~/Src/Default.aspx"

The application's main folder is C:\Program Files\Software Productivity Research LLC\KnowledgePLAN and the aspx files are in C:\Program Files\Software Productivity Research LLC\KnowledgePLAN\src.

When I registered the application in the Cassini Web Server Explorer, I made the Physical Location C:\Program Files\Software Productivity Research LLC\KnowledgePLAN\ and the Default Document \src.

Any thoughts on this?

Thanks for the response. My Default Document setting is src\default.aspx. I guess I did not proof read my question to you well enough (typo). However, I did what you suggested and in fact the url when the login page is up is:

http://localhost:31454/src/login.aspx?ReturnUrl=%2fDefault.aspx

Which explains why it is looking for \Default.aspx instead of src\Default.aspx.

When I use the described roundabout way thru our Recover Password page and then go back to the login page, the url is correctly:

http://localhost:31454/Src/Login.aspx?ReturnUrl=%2fSrc%2fDefault.aspx

This started me thinking why is the initial url incorrect when the Cassini Default Document setting is src\default.aspx. Well, it turns out, for some reason, that although I entered what is the correct registration information when there were no other registration entries, when I exit the Cassini Web Server Explorer and then launch it again, a second entry was there with the Default Document setting set to \default.aspx. When I changed the Default Document to src\default.aspx in this additional (magic) entry, everything worked fine.

I had played around with a few registrations before I got it right and most certainly one of the incorrect ones had the Default Document as \default.aspx. I definitely unregistered all the incorrect ones but for some reason it re-appeared when I added the good one.

Any thoughts on this?

I could not find CassiniMetabase.xml on my Vista machine. However, I did the following:

1. I unregistered everything and exited the Cassini Web Server Explorer.
2. I uninstalled my application.
3. I reinstalled my application.
4. I ran the application and it launched successfully but my login problem existed. It seems strange that it launched since in theory the application was not registereed with Cassini.
5. I went into the Cassini Explorer and the application entry was once again there. Magic. I simply then changed the Default Document setting from \default.aspx to src\default.aspx.
6. I ran my application and all was well.

It appears that the first entry I put into the Cassini Explorer when I first installed the web server will not go away.

This is not doing me any harm but it would be nice to know what is going on.

Sorry I disappeared. I was on vacation last week. I found CassiniMetabase.xml in c:\programdata\ultidev. Apparently I needed to incude non-indexed and hidden files in my Windows Explorer search. It looks as follows:

<?xml version="1.0" encoding="utf-8" ?>

</CassiningMetabase>

I do not have the time today to play around with it but I will as soon as I can.

When I unregister my application, the XML file is as follows:

<?xml version="1.0" encoding="utf-8" ?>
- <CassiningMetabase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<DefaultDocument />
<ApplicationID>4fd8b3f7-bc73-4583-95fe-e7b69b10a3ae</ApplicationID>
</Application>
</CassiningMetabase>

I then uninstall my application and the XML file is as follows:

<?xml version="1.0" encoding="utf-8" ?>
- <CassiningMetabase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<DefaultDocument />
<ApplicationID>4fd8b3f7-bc73-4583-95fe-e7b69b10a3ae</ApplicationID>
</Application>
</CassiningMetabase>

I then re-install my application and the XML file is as follows:

<?xml version="1.0" encoding="utf-8" ?>
- <CassiningMetabase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<DefaultDocument />
<ApplicationID>4fd8b3f7-bc73-4583-95fe-e7b69b10a3ae</ApplicationID>
</Application>
</CassiningMetabase>

Note that even though my application is unregistered, the entry is back in the XML file. Also note that the DefaultDocument is Default.aspx which was what I used when I first started playing with Cassini. If I change it to src\default.aspx all is well as indicated below:

<?xml version="1.0" encoding="utf-8" ?>
- <CassiningMetabase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</Application>
</CassiningMetabase>

This is not causing me a problem but it would be nice to know what causes this.

I did not know that when I re-installed my application, it would re-register itself. The fact that the DefaultDocument gets set to Default.aspx instead of src\Default.aspx makes sense. All that I need to do is to edit the registration entry to correct this. Thanks for your help.
