Administering Connections V5.5Welcome to the IBM Connections V5.5 documentation. IBM Connections is social networking software designed for the workplace. Its features help you to establish dynamic networks that connect you to the people and information you need to achieve your business goals.
AdministeringRun administration and maintenance tasks to keep your environment up-to-date. For example, learn how to customize your deployment or how to use the wsadmin utility to edit configuration files. You can also schedule tasks, maintain application databases, moderate content, or manage users and their roles.
Disabling widgetsYou can disable widgets from displaying on the Home page or elsewhere in IBM® Connections when you no longer want them to be available to your users.
Editing widgetsEdit a widget to change its name, description, or deployment descriptor.
Removing widgetsIf a third-party widget is no longer used or needed, you can remove it from the widget catalog. You cannot remove IBM® Connections widgets from the catalog, you can only disable them.
Administering ProfilesProfiles provides two types of administrative capabilities: configuration settings and administrative commands. You change configuration settings and execute administrative commands by running scripts from the wsadmin command line.
Making photos cachable in secure environmentsIf your Profiles deployment is configured to prevent profile data from being accessible to readers, you can opt to make just user photos cachable.

Making photos cachable in secure environments

If your Profiles deployment is configured to prevent profile data from being accessible to readers, you can opt to make just user photos cachable.

Before you begin

This is an optional task; it is only useful if Profiles is configured to lock profile data. For security reasons, when the reader role is set to something other than everyone, Profiles does not publicly cache photos. As a result, no profile photos are visible to readers. If you want to override this behavior and make photos visible, you must define a rule in the IBM® HTTP Server's configuration file to explicitly set the caching headers of photos.

Procedure

Define a rule in the IBM HTTP Server to explicitly set the caching headers of profile photos by completing the following steps:

Using a text editor, open the httpd.conf file, which is the IBM HTTP Server configuration file. The file is stored in the following directory by default:
- AIX®: /usr/IBM/HTTPServer/conf
- Linux™: /opt/IBM/HTTPServer/conf
- Microsoft™ Windows™: C:\IBM\HTTPServer\conf

Add the following block of code to the httpd.conf file:

<LocationMatch  /*/profiles/photo.do >
  <IfModule mod_headers.c>
    Header set Pragma ""
    Header set Cache-Control "max-age=21600,s-maxage=21600,public"
  </IfModule>
</LocationMatch>

Save and close the configuration file.
Restart the IBM HTTP Server.
