Abstract: Website load testing using agents is disclosed. An address of a website and a window of time in which to perform a load test are received. The address and the window of time are distributed to a plurality of remotely operating agents, distributed over a wide area. Each agent in the plurality is to access the website at the received address during the window of time to load test the website. Data from the plurality of agents is received upon passage of the window of time, describing a load placed upon the website by the plurality of agents. The received data describing the load placed upon the website is presented. Alternatively, a script may be used to load test a website, the script a series of commands to be executed across the website as a simulation of a transaction, the script to be executed in the window of time.

Abstract: Changes to files in a master source file set on a master computer are identified. Local host addresses of the files are converted to uniform resource locators. The identified changes are stored in a modification list comprising the uniform resource locators specifying changed files of the master source file set. The modification list is transmitted to one or more computers, notifying the one or more computers that the master source file set has changed. A response is received from at least one of the one or more computers, indicating that the identified changes are installed. An alert is issued indicating that a copying of the changes by an agent in at least one of the one or more computers has failed, to cause a traffic manager that redirects traffic to decrease requests made to a web server on the computer having the agent.

Abstract: Methods for determining the level of volatile components, such as essential oils, in a food composition, such as a food processing stream, by analysis of a vapor containing the component. The vapor may be transferred from the headspace of a food processing stream to an analyzing station where the levels of volatile components are determined. Alternatively, the vapor may be generated by sparging a sample of the food or related processing stream for analysis thereof. Analysis of the components maybe performed by spectroscopic methods on a continual or periodic basis.

Abstract: This invention relates to managing multiple web servers, and more particularly to a web service system and method that allows a system operator to distribute content to each web server in the web service system and notifying a computer, such as a cache server, of content changes. In one embodiment, a method for notifying a computer of changed files includes identifying changes in a source file set, storing the identified changes in a modification list comprising uniform resource locators specifying the changed files, and transmitting the modification list to a computer. In another embodiment, a method for replicating changes in a source file set on a destination file system and for notifying a computer of the changes includes identifying changes in a source file set, storing the changes in a first modification list, and transmitting the first modification list to an agent having access to a destination file system.
