Servlet Filters

The absolute redirects filter is used to ensure that all redirects are absolute. It should not be disabled because it also sets the company id in the request so that subsequent calls in the thread have the company id properly set. This filter should also always be the first filter in the list of filters.

com.liferay.portal.servlet.filters.absoluteredirects.AbsoluteRedirectsFilter=true

The audit filter populates the AuditRequestThreadLocal with the appropriate request values to generate audit requests.

com.liferay.portal.servlet.filters.audit.AuditFilter=false

The auto login filter processes the classes in the property auto.login.hooks to provide auto login functionality.

com.liferay.portal.servlet.filters.autologin.AutoLoginFilter=true

The cache filter caches processed web content. See ehcache.xml to modify the cache expiration time to live.

com.liferay.portal.servlet.filters.cache.CacheFilter=true

The CAS filter is used to provide CAS based single sign on.

com.liferay.portal.servlet.filters.sso.cas.CASFilter=true

The char buffer pool filter enables char buffer pooling to minimize garbage collection of large char arrays. See the system property com.liferay.portal.kernel.util.StringBundler.unsafe.create.limit.

com.liferay.portal.servlet.filters.charbufferpool.CharBufferPoolFilter=false

This double click filter will prevent double clicks at the server side. Prevention of double clicks is already in place on the client side. However, some sites require a more robust solution. This is turned off by default since most sites will not need it.

com.liferay.portal.servlet.filters.doubleclick.DoubleClickFilter=false

The dynamic CSS filter is used to parse Sass CSS.

com.liferay.portal.servlet.filters.dynamiccss.DynamicCSSFilter=true

The ETag filter is used to generate ETag headers.

com.liferay.portal.servlet.filters.etag.ETagFilter=true

If the user can unzip compressed HTTP content, the GZip filter will zip up the HTTP content before sending it to the user. This will speed up page rendering for users that are on dial up.

com.liferay.portal.servlet.filters.gzip.GZipFilter=true

The header filter is used to set request headers.

com.liferay.portal.servlet.filters.header.HeaderFilter=true

The ignore filter will ignore certain files from being accessed directly from a browser.

scom.liferay.portal.servlet.filters.ignore.IgnoreFilter=true

The I18n filter is used to internationalize URLs. See the property locale.prepend.friendly.url.style for more information.

com.liferay.portal.servlet.filters.i18n.I18nFilter=true

The Language filter replaces JavaScript code that make a client side call to translate a piece of text with the actual translated value. For example, a typical piece of JavaScript code fits the pattern Liferay.Language.get('key') where 'key' is the text to translate. This filter will replace the entire piece of code with the translated text. This is very useful because it will lower the number of client calls by translating the text before the browser receives the JavaScript file.

com.liferay.portal.servlet.filters.language.LanguageFilter=true

The minifier filter is used to minify CSS and JavaScript.

com.liferay.portal.servlet.filters.minifier.MinifierFilter=true

The monitoring filter monitors portal request performance.

com.liferay.portal.servlet.filters.monitoring.MonitoringFilter=true

The NTLM filter is used to provide NTLM based single sign on.

com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter=true

The NTLM post filter is used to fix known issues with NTLM and ajax requests. See http://issues.liferay.com/browse/LPS-3795.

com.liferay.portal.servlet.filters.sso.ntlm.NtlmPostFilter=true

The OpenSSO filter is used to provide OpenSSO based single sign on.

com.liferay.portal.servlet.filters.sso.opensso.OpenSSOFilter=true

The secure filter is used to protect servlets based on IP and protocol. See the properties *.servlet.hosts.allowed and *.servlet.https.required.

com.liferay.portal.servlet.filters.secure.SecureFilter=true

The servlet authorizing filter allows external servlets to be authorized by the portal. See http://issues.liferay.com/browse/LEP-4682.

com.liferay.portal.servlet.filters.servletauthorizing.ServletAuthorizingFilter=true

The session id filter ensures that only one session is created between http and https sessions. This is useful if you want users to login via https but have them view the rest of the site via http. This is disabled by default. Do not enable this unless you thoroughly understand how cookies, http, and https work.

com.liferay.portal.servlet.filters.sessionid.SessionIdFilter=false

The Sharepoint filter allows users to access documents in the Document Library directly from Microsoft Office using the Sharepoint protocol.

com.liferay.portal.sharepoint.SharepointFilter=true

The strip filter will remove blank lines from the outputted content. This will speed up page rendering for users that are on dial up.

com.liferay.portal.servlet.filters.strip.StripFilter=true

The theme preview filter generates a preview of the currently applied theme that can be used by the Dreamweaver Theming plugin. This is disabled by default. Set the themePreview parameter to 1 in the URL to access the theme preview for any page. For example, a URL can be http://localhost:8080/web/guest?themePreview=1.

com.liferay.portal.servlet.filters.themepreview.ThemePreviewFilter=false

The thread dump filter will automatically log thread dumps when the portal is too slow. Behavior can be configured via the property thread.dump.speed.threshold.

com.liferay.portal.servlet.filters.threaddump.ThreadDumpFilter=false

The thread local filter cleans up short lived thread locals managed by CentralizedThreadLocal to prevent memory leaks.

com.liferay.portal.servlet.filters.threadlocal.ThreadLocalFilter=true

The unsynchronized print writer pool filter enables pooling print writers to minimize the creation of java.io.PrintWriter instances because it is an expensive action.

com.liferay.portal.servlet.filters.unsyncprintwriterpool.UnsyncPrintWriterPoolFilter=true

The valid HTML filter will move JavaScript that is outside of the closing body tag to its proper place inside the body tag. Most sites will prefer to leave this filter disabled because having JavaScript outside of the body tag causes the page to render faster. However, the side effect is that it will also make the site unaccessible to screen readers because the HTML is technically invalid. Setting this property to true optimizes for accessibility while setting this property to false optimzes for browser performance.

com.liferay.portal.servlet.filters.validhtml.ValidHtmlFilter=false

The virtual host filter maps hosts to public and private pages. For example, if the public virtual host is www.helloworld.com and the friendly URL is /helloworld, then http://www.helloworld.com is mapped to http://localhost:8080/web/helloworld.

com.liferay.portal.servlet.filters.virtualhost.VirtualHostFilter=true
