Notes on Log Files

For Web Hosting Linux packages and Managed Dedicated Servers

Log data can be found in the logs directory of your web space in the files access.log.CW.gz for the past weeks and access.log.CW.D.gz for the current week.

  • CW stands for calendar week.

  • D stands for day (starting with 1 for Monday to 7 for Sunday).

  • .gz means that the file is compressed to save space.

The logs for the current day are updated almost in real time. Due to the large amount of data, log data is kept available for a maximum of 8 weeks.

The space used by the access logs is ignored when determing your remaining storage space. There is no need to delete the "logs" folder in order to have more storage space.

Calling a page via a proxy server

If websites are accessed via a proxy, the proxy establishes a connection to the desired website and passes it on to your own computer.

The proxy server functions as a sort of representative, requesting the pages and forwarding them to the user. Consequently, the IP address of the proxy and not the address of the workstation that originally requested the page is in the log file.

To make it possible to trace the origin of a request when accessing it via proxies, some proxies send a header field called X-Forwarded-For, in which the original IP is then entered. This X-Forwarded-For header is appended to the end of each entry in the log file.

If using the 1&1 IONOS SSL proxy, and the corresponding information is available, the IP address of the computer actually requesting the file or page is in the last column of each log line.
This improves the possibility of creating meaningful visitor statistics.

Please note: Due to data protection guidelines on personal data, the IP address of the visitors are anonymized in the log files.
