architecture provides a new Web page paradigm
applications displays in a series of Web pages that needs a distinct download
for each page, this is called web page paradigm. On the other hand RIA takes no
longer time in downloading the page because the client engine may be prefetching

been formulated RIA that reflects user?s experience initiated by an HTTP GET
request to permit reporting of response time. RIA developers must instrument
their application code to produce the measurement data needed for SLM.
status of RIA development and adoption
At present RIAs are
still in the early stages of development and user adoption that still have a
number of restrictions and requirements remaining in it. These are:
- Browser approval:
Many RIAs need modern web browsers for running that include Advanced
client-server communication and DOM Scripting and advanced CSS techniques to

- Development tools:
To build RIA, some essential products require including some Ajax Frameworks

needs technical approaches that limit applications? accessibility.
- User?s acceptance: Users expecting standard web
applications may find that some unexpected browser functionality e.g.
