FIX: Web cache files are overwritten if you connect through Visual Studio .NET to multiple Web sites that use IP addresses or host headers that reside on the same server

This article has been archived. It is offered "as is" and will no longer be updated.
When Microsoft Visual Studio .NET opens a Web project, Visual Studio .NET tries to use one cache location for all URLs that appear to be the same. For example, the URLs http://localhost, http://localhost:80, http://localcomputername, and all locate the root folder of the Web server on the same local computer. Visual Studio .NET tries to use one cache location that has the name of the local computer for all these URLs.
The problem occurs if the computer has more than one IP address and each Web site uses a separate IP address. The reverse lookup to obtain the computer name returns the same name for each IP address. Therefore, all the Web sites that use IP addresses on the same computer share the same offline cache location. This behavior may cause data loss and other related problems.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Visual Studio .NET 2003 service pack that contains this hotfix.
