Web.config project override

[WynneSMI]

I have a problem trying to override the timeout settings in the Web.config file of a specific project. We have our site setup so everyone logs into our login page, /login/login.aspx and the Web.config for that project is set to
<authentication mode=&quot;Forms&quot;>
<forms name=&quot;login&quot; path=&quot;/&quot; loginUrl=&quot;/login/login.aspx&quot; protection=&quot;All&quot; timeout=&quot;90&quot; />
</authentication>

<authorization>
<deny users=&quot;?&quot; />
</authorization>
After logging in, the user has access to certain apps depending on permissions, etc. The timeout is set to 60 minutes in this project, which all the other projects below the login folder (example: login/app1, login/app2, etc.) inherit the 60 minute timeout. I have a specific project in which I want to override this timeout property just for this project but I can't seem to get it to work. I've tried modifing the Web.config for this project, but it doesn't seem to work.. Does anyone know how to do this? Thanks!
