Symptoms
When you use the Load method of the XMLDOM object model to synchronously load an Extensible Markup Language (XML) document on a client computer over an SSL connection, the method fails with error 0x800c0007 and the INET_E_DATA_NOT_AVAILABLE return value.
Cause
This problem occurs when the file is not cached on the client computer. There are several reasons why the file may not be cached:
-
The user selects the Do not save encrypted pages to disk check box on the Advanced tab of the Internet Options dialog box.
-
The server sends a Pragma:no-cache or Cache-control:no-cache header.
-
If you are using Microsoft Internet Information Server (IIS), the Content-Expiration option is set to Expire Immediately, which sends no-cache headers as well as the Expires:0 http header.
Resolution
To resolve this problem, perform the following steps:
-
In Internet Explorer, on the Tools menu, click Internet Options. On the Advanced tab, clear the Do not save encrypted pages to disk check box.
-
Make sure that the server does not send no-cache headers.
-
In IIS, in the Microsoft Management Console (MMC) snap-in, right-click the XML file. On the HTTP Headers tab, turn off the Content-Expiration option.
Status
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
