RE: [syndication] Re: RSS / RDF cache

(I don't have the original message so I am replying to the reply):

The most recent parser still uses the WinInet cache, unless you
use the ServerHttp object.

It is possible to explicitly flush a URL from the cache using the
DeleteUrlCacheEntry API. Here is a VB snippet:


Public Declare Function DeleteUrlCacheEntry Lib "Wininet.dll" _
  Alias "DeleteUrlCacheEntryA" (ByVal lpszUrl As String) As Boolean

'
' RemoveFromCache -
'
'   Delete the given URL from the browser cache. Return True if removed,
False
'   otherwise.
'

Public Sub RemoveFromCache(strURL As String)
  Dim bRemoved As Boolean
  bRemoved = DeleteUrlCacheEntry(strURL)
End Sub

Jeff;

Paul,

It sounds like you may not be using the most recent MS XML Parser.  Earlier
ones used an HTTP library that was riddled with problems from a server
perspective, especially related to caching and proxy server acess.     I
have some code you can use at

http://www.wc.cc.va.us/services/news/

It's a service that runs using ASP.  The source code for the main file is
freely available and deals with all varieties of RSS.
