SYMPTOMS
When you create a Web application filter that adds headers to a request, the filter may generate an &quot;out-of-memory&quot; error or a &quot;not enough storage&quot; error. This problem may occur even though the header size is very small. This problem may also occur when you use the Internet Information Services (IIS) 5.0 Secure Sockets Layer (SSL) filter.



CAUSE
This problem occurs because IIS 5.0 incorrectly counts the entity data as part of the header data. This prevents the AddHeader function and SetHeader function from working correctly, and that causes filters that add headers to fail with &quot;out-of-memory&quot; or &quot;not enough storage&quot; errors.

This problem occurs with the SSL filter because when the filter decrypts a message, it must use the ReadNext function to fill the buffer with sufficient data to form a complete SSL message before the decryption can succeed. Some browser client programs, including Microsoft Internet Explorer, sometimes encrypt both the headers and the body of a POST message or PUT message at the same time. This requires that the SSL filter must buffer the whole request before it can decrypt the message.
