BUG: GetServerVariable Causes an Access Violation in Internet Security and Acceleration Server Web Filter (330639)
The information in this article applies to:
- Microsoft Internet Security and Acceleration Server 2000
- Microsoft Internet Security and Acceleration Server 2000 SP1
This article was previously published under Q330639 SYMPTOMS
If you call the GetServerVariable method in the Microsoft Internet Security and Acceleration (ISA) Server Web filter, you may cause an access violation.
RESOLUTION
To work around this problem, register the filter so that it can handle the SF_NOTIFY_PREPROC_HEADERS notification. You can leave the notification handler empty.
STATUSMicrosoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
The access violation may occur when you call GetServerVariable to retrieve a value for HTTP_ALL, RAW_HTTP, HTTP_REFFERER, and other variables. GetServerVariable can cause an access violation when it is called in any notifications, unless the filter handles SF_NOTIFY_PREPROC_HEADERS.
