I have a URL property type on an Optimizely block that could be an external URL or media item.
When rendered, the the URL is of the format: /link/some_kind_of_id.aspx
That relative URL will work, as the Epi HTTP handler will determine if it's a media item or not, and return whatever the resource is.
What I need to do is programmatically use this ID to determine if the URL is that of an uploaded media item so I can get the filename of the uploaded media item and do some additional processing.
However, I can't find any information in any old or new Epi/Opti documentation/guides.
I was hoping I could use something like the ContentLoader to get the content or the BlobFactory. The former requires a content link and the latter requires a GUID - I have neither.
Is there any way I can programmatically get more info from a URL property value via it's "UriInternal" link?
TIA
