The following members return UrlAccessRule objects:

• UrlAccessRule.Allow(String[])
• UrlAccessRule.Deny(String[])

Remarks

Define a UrlAccessRule to allow or deny resource load from all/specific URLs. You can use the static Allow(String[]) or Deny(String[]) method to create URL access rules. Use the SetRules(IAccessRule[]) method to register these rules in your application.

Examples:

C#

// Image load from URLs is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow());

VB.NET

' Image load from URLs is allowed
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow())

C#

// Image load from URLs is denied
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Deny());

VB.NET

' Image load from URLs is denied
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Deny())

C#

// Image load is allowed only from the specified URL
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow("http://mysite.dev"));

VB.NET

' Image load is allowed only from the specified URL
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Allow("http://mysite.dev")"))

C#

// Image load from the specified URL is denied
// Images from other URLs are accessible
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Deny("http://mysite.dev")); 

VB.NET

' Image load from the specified URL is denied
' Images from other URLs are accessible
DevExpress.Security.Resources.AccessSettings.StaticResources.SetRules(UrlAccessRule.Deny("http://mysite.dev"))
