Workshop

The workshop is designed to help you anticipate possible questions, review what you've learned, and begin learning how to put your knowledge into practice.

Quiz

1:

How would you avoid logging hits from a client accessing your Web site from a particular network?

2:

How can you log images to a different file?

Answers

A1:

In some situations, you may want to ignore requests coming from a particular network, such as your own, so that they do not skew the results. You can do this either by post-processing the logs and removing them or by using the SetEnvIf directive:

SetEnvIf Remote_Addr 10\.0\.0\. intranet
CustomLog logs/access_log "%h %l %u %t \"%r\" %>s %b" !intranet

A2:

Earlier in the chapter, you learned how to avoid logging images. Instead of ignoring images altogether, you can easily log them to a separate file, using the same environment variable mechanism:

SetEnvIf Request_URI "(\.gif|\.jpeg)$" image
CustomLog logs/access_log common env=!image
CustomLog logs/images_log common env=image
