Compressing an HTTP Response within Confluence
Confluence supports HTTP GZip transfer encoding. This means that Confluence will compress the data it sends to the user, which can speed up Confluence over slow or congested Internet links, and reduce the amount of bandwidth consumed by a Confluence server.
Turn on Confluence's GZip encoding if:
- Users are accessing Confluence over the Internet, or a WAN connection with limited bandwidth.
- You wish to reduce the amount of data transfer between the Confluence server and client.
If you are accessing Confluence over a Local Area Network or over a particularly fast WAN, you may wish to leave GZip encoding disabled. If the network is fast enough that transferring data from Confluence to the user isn't a limiting factor, the additional CPU load caused by compressing each HTTP response may slow Confluence down.
Enabling HTTP Compression
- Choose the cog icon , then choose General Configuration under Confluence Administration.
- Select 'General Configuration' in the left-hand panel.
- Enable 'Compress HTTP Responses'.
It is possible to configure which types of content are compressed within Confluence. By default, the following mime types will be compressed:
If you wish to change the types of content to be compressed, add a replacement
urlrewrite-gzip-default.xml file within the
WEB-INF/classes/com/atlassian/gzipfilter/ directory in your Confluence Installation Directory. A sample file is provided as an attachment. It is unlikely that you will need to alter this file.
