Examples

Request IsPosted, IsPreview, IsLocal etc. Examples

All the request.is(...) viper methods check for a specific type of information about the type of the request. Is it an AIM request (request wihin the AIM channel), is it an Json request (mime contenttype equals application/json), is it a preview (the request is rendered in preview mode and thus originating from the cms manager).

These vipers are particularly useful to make exceptions within your sxml logic when needed. Notice that some of these vipers will be available as of iXperion release 1.2.

Using PageTranslations to preview items which use sessions.

In this example sessions will not be touched while previewing an item. Preventing the following preview error: "Unable to use sessions because the item is not rendered by Asp.Net. You are probably previewing an item that uses sessions. This is not yet supported."
