ILogPlugin::QueryExtraLoggingFields
The ILogPlugin::QueryExtraLoggingFields method determines logging information that is specific to a custom logging module.
virtual HRESULT STDMETHODCALLTYPE QueryExtraLoggingFields(
PDWORD cbSize,
PCHAR szParameters
);
Parameters
cbSize
The size of the szParameters parameter.szParameters
Null-delimited strings that list the extra fields to be logged.
Remarks
You can use this method to record data sent by custom headers from the client. For example, to capture a client's user agent string and HTTP cookie, the szParameters parameter would contain the following:
User-Agent:\0Cookie:\0\0
You could then use the IInetLogInformation::GetExtraHTTPHeaders method to retrieve a list of header information. This list would be null-delimited.
