Abstract: The present invention discloses a system and method to allow a browser frame, tab, or window to communicate with an arbitrary number of application hosts in different domains while keeping its location constant on a client host. The invention allows all communications to occur between the web browser and any of the applications hosts and the client host while the hosts do not to have any knowledge of each other and cannot exchange data between them. The present invention thereby allows the frame, tag, or window to persist arbitrary data and programs. The system specifically allows sending arbitrary HTTP messages to the application hosts and allows receiving the associated responses, while allowing every interaction with the client host that the user browser supports (e.g. HTTP, Ajax), and allowing continuous execution of a program in the user browser frame, tab, or window.

Abstract: A catalyst used in the reaction of oxidative bromination of methane is provided. The catalyst is prepared by the following procedures: mixing at least one of the precursors selected from the compounds of Rh, Ru, Cu, Zn, Ag, Ce, V, W, Cd, Mo, Mn, Cr and La which can dissolve in water with the Si precursor, hydrolyzing, drying and sintering. In the catalysis system, methane reacts with HBr, H2O and oxygen source (O2, air or oxygen-rich air), finally CH3Br and CH2Br2 are produced. Another catalyst used in the reaction of condensation of methane bromide to C3-C13 hydrocarbons is also provided. This catalyst is prepared by supporting compounds of Zn or Mg on molecular sieves such as HZSM-5, HY, Hb, 3A, 4A, 5A or 13X et al. With this catalyst, CH3Br and CH2Br2 produced in the former process can react further to give C3 to C13 hydrocarbons and HBr, and HBr can be recycled as a medium.
