It is an attempt to hook up with some internal data gathering functions in IIS and hence collect probe data for further analysis. IIS Probe collects following information today: 1) IIS File Hash table configuration and usage 2) IIS Allocation Cache Data 3) WAM statistics for multiple instances 4) Object Sizes (static) for various IIS objects IIS probe, being an ISAPI dll can be accessed remotely from any browser and also supplies dynamic data without much overhead. Install iisprobe.dll by just copying it to any directory marked with execute permission. For example: Copy it to the /scripts directory. Access it via the browser by typing http:.///scripts/iisprobe.dll? and follow the instructions in menu persented. ************************************************************/ BOOL ParseAndDispatch( IN EXTENSION_CONTROL_BLOCK * pecb); DWORD HttpExtensionProc( EXTENSION_CONTROL_BLOCK * pecb ) { BOOL fReturn = TRUE; char buff[2048]; // // Note the HTTP header block is terminated by a blank '\r\n' pair, // followed by the document body // wsprintf( buff, "Content-Type: text/html\r\n" "\r\n" "IIS Probe Page\n" " This page contains diagnostic information" " useful for development - for IIS 4.0 & beyond \n" "
