Log205

Log205 refers to a specific entry type within application and system logs that record HTTP 205 Reset Content responses. The HTTP 205 status code, defined in RFC 7231, instructs the client that the server has fulfilled the request and the user agent should reset the document view which caused the request. In web applications, a 205 response often follows the successful submission of a form or the completion of a command that does not need to return additional data.

When servers generate logs, a "log205" line typically contains the timestamp, the request identifier, the client's IP address, the URI requested, and the 205 status code. Additional fields may include the user agent string, the session identifier, and any application-specific diagnostics. Analysts use the log205 entries to monitor the frequency of reset operations, to identify patterns of repeated form submissions, and to troubleshoot issues where the client does not correctly reset its state.

In many logging frameworks, the numeric code is mapped to a textual description. For example, the Apache HTTP Server has the "AccessLog" format that can be configured to write "205" directly, whereas more verbose systems might translate it to "Reset_Content". Legacy systems sometimes log the entry under the broader category "RESET" or "STATE_RESET".

Because the 205 status code rarely carries a message body, log205 entries are concise but important for understanding user interactions that rely on state reset logic. By aggregating these logs, administrators can detect potential security or usability problems associated with state management in web applications.
