Abstract: Techniques are described herein for determining completion of a Web server download session at a database server. A Web server initiates a download session for downloading a requested resource (e.g., a file or an output of an executable) to a client. The download session includes download operation(s), each corresponding to a respective portion of the requested resource. The Web server incorporates a session-specific identifier indicative of the download session and/or byte range indicator(s) corresponding to the respective download operation(s) into Web server log files. The database server uses the session-specific identifier and/or byte range indicator(s) to determine that the download operation(s) are included in the download session. The database server determines a download pattern corresponding to the download session based on download request(s) that correspond to the download operation(s).
