Bolero has the ability to filter out unwanted URLs based on their extension. This feature can dramatically reduce the size of the Bolero database.
Filtering information is found under the URL Extension Filtering subsection of the Bolero Settings file. The default Settings file looks like this:
This list specifies that URLs with these extensions should be logged. <None> specifies to include URLs that do not have extensions. Any URL not listed is always logged by Bolero.[URLExtensionFiltering] bin = Include gif = Include hqx = Include htm = Include html = Include jpeg = Include jpg = Include moov = Include <None> = Include
Note
URL Extension Filtering is case sensitive. For example, you can have both 'gif' and 'GIF' as file extensions, if you want to distinguish between these extensions. If you instruct Bolero not to log 'gif' files, it will still log 'GIF' files.
The number of 'gifs' on the Web server you are logging could be quite extensive; we recommend that you do not log 'gifs'.
The list of URL extensions in this section is a sample set only; you can add or remove any extensions. If an extension is not listed here, Bolero's default behaviour will be to 'Include' that URL when logging from the Web server. Changing a URL extension's default value from 'Include' to 'Exclude' instructs Bolero to ignore all log entries containing URLs ending in those extensions.
For example, if you wish to disable logging of all URLs with the extension 'gif' and the extension 'wav', add and/or modify the Bolero Settings file:
[URLExtensionFiltering] gif = Exclude wav = Exclude
Note
A similar feature to URL Extension Filtering is URL Filtering. This feature allows you to selectively disable logging of a particular URL, rather than a set of URLs based on their extension. Revisions to the URL Filtering section are done online, not in the Settings file.
