A message originator, such as an author of an email, can designate “section access settings” which can selectively permit or deny access of portions of the email's content. Recipients who are not authorized may not exercise the access right upon the designated portion of content. For example, an access right may allow displaying a section of text in an email message only for specified recipients and not to other recipients. In a preferred embodiment, the entire email content, including restricted portions, is provided to all recipients, including unauthorized recipients. Unauthorized recipients are prevented from exercising the access right even though the restricted portion has been received.

A method, a system and a computer program product are disclosed for allocating bandwidth of a limited bandwidth link to dataflows containing packets. In the method, the number of buckets is adaptively adjusted dependent upon the number of active dataflows. Each bucket has a number of tokens allocated to the bucket for use by the corresponding dataflow. The number of tokens is dependent upon a weighted value for the corresponding dataflow. Queueing of the packets for utilization of the limited bandwidth link is dependent upon the tokens. Tokens are then adaptively-reallocated to one or more buckets in accordance with a weighted value for each of the dataflows.

Techniques for provisioning and decommissioning web servers in an automated manner. In one embodiment, a threshold value relating to an operational metric of a web server can be stored. The metric can be monitored as the web server receives requests. If the metric exceeds the threshold value, additional web servers can be automatically provisioned to handle a portion of the requests. If the metric falls below the threshold value, the additional web servers can be automatically decommissioned. In another embodiment, information can be logged pertaining to web server requests received over time. Based on this information and a threshold value, patterns of high/low server load can be determined and a policy can be generated identifying time intervals during which additional web servers should be provisioned (or existing web servers should be decommissioned). The policy can be used at server runtime to provision or decommission web servers at the identified intervals.
