Two-way communication between AppDomains inside of IIS Requests

by

I’m working on an ASP.NET app, and we want to add the ability to call customer script during some of the requests. Since we don’t trust this script, we are spawning a child AppDomain inside of our IIS request which has limited permissions, and loading both the customer assembly and a Script Runner assembly. The customer script can do things like change the description of a business object or change a status code to an error if certain criteria are met. Because the changes are so varied, I can’t encompass them in a single object that gets returned from a method call. As the script is running, I need it to alter values in objects inside of the Request that launched this child.

Disable GZIP compression for IE6 clients

by

We need to conditionally disable GZIP compression if user’s browser is IE6 (it hangs browser for 5min) in few pages of larger site. Server is IIS7 and has compression for static content turned on – want that compression left working if user agent is not Mozilla/4.0. ASPX code sample anyone?
Alternatively, code to conditionally redirect to the same page on another site (could create another virtual site with compression disabled) but need to pass all parameters (GET/POST).

runAllManagedModulesForAllRequests = “true” killing windows authentication in IIS7

by

We have windows authentication set up on our staging server for our clients to help prevent google from indexing our staging URLs. We recently found out that one of our sites is seemingly ignoring our IIS settings (anonymous authentication is disabled, windows authentication is enabled). We ended up figuring out that removing the setting runAllManagedModulesForAllRequests=”true” on the modules node (which is required for our URL rewriting on the site) fixes the issue and the windows login/password box appears as expected when we browse to the site. If we keep the setting there, the site allows any anonymous user to browse the website.
