cassini, forms authentication and application folder [2.0]

[Wiktor Zychla [C# MVP]]

Hi,

I struggle for over an hour with the integrated Cassini web server. the
problem I am facing is as follows:

when I turn forms authentication on in the web.config file, the website
seems to be running in the context of a wrong directory. images, style
sheets and jscripts files placed in app directory (or in subdirectories)
suddenly become invisible to the application. when I move the application to
the IIS, it works as expected but I like the light-weight of Cassini and
still wish to use it for development.

steps to reproduce behavior:

1. create new web application to be run under cassini
2. add two forms, default.aspx and login.aspx
3. on both forms add an image container:
<img src="testimage. jpg" />

where testimage.jpg resides in the application root folder.

3. set the authentication to "Windows"

4. on default.aspx add a Button and place

Response.Redire ct( "login.aspx " );

you will see that the image is correctly visible on both forms even if a
redirect takes place.

5. change the authentication to "Forms" with

<authenticati on mode="Windows">

<forms loginUrl="login .aspx" name="AuthCooki e" timeout="60" path="/"
protection="All " />

</authentication >

6. run the application. after the Forms Authentication redirects you to the
login page, you will see that the image container in login.aspx is empty.

even if you manually disable redirect for the default.aspx:

<location path="Default.a spx">
<system.web>
<authorizatio n>
<allow users="?"/>
</authorization>
</system.web>
</location>
the image is still invisible.

is there a simple and clever way to overcome this issue?

thanks in advance,

Wiktor

Wiktor,

You were on the right track in attempting to grant all users access to the
root structure, but access is granted from the top down. In other words you
need to allow all first and then limit pages afterward. The first item in
the security settings overrides all others.

that's it. thanks a lot.

I thinks that for security reasons I will rather do in in an oposite way:
deny all first but configure selected items for unrestricted access. anyway,
this works now. thanks again.
