ASP.NET Syntax   ASP.NET Configuration Sections

---

Configures the set of code access security permissions applied to a particular application. The <trust> section can be declared at the machine, site, and application levels.

<trust
   level = "Full | High | Low | None"
   originUrl = "url"
/>

The <trust> tag supports two attributes.

Attribute	Option	Description
level		Specifies the security zone under which the application will be run.
	Full
	High
	Low
	None
originUrl		Specifies an application’s URL of origin. If present, this can be used for some permissions, such as Socket and WebRequest, that allow connectivity back to the host of origin. This allows permissions that rely on the notion of a host to function correctly.

The following example specifies trust level settings for an ASP.NET application.

<securityPolicy>
   <trustLevel name = "Full" policyFile = "internal" />
   <trustLevel name = "High" policyFile = "web_hightrust.config" />
   <trustLevel name = "Low"  policyFile = "web_lowtrust.config" />
   <trustLevel name = "None" policyFile = "web_notrust.config" />
</securityPolicy>
