By default every web resource program generated output/response content will be stored in the buffer before it is getting displayed on browser window as web page content. Due to this browser window may show old output collected from the buffer even though the web resource program of web application is capable of generating new and updated output.   


* To solve the above problem instruct browser window for not storing the output in the buffer from web resource program through web server by using response headers as shown below.

res. setHeader (“cache-control”, “no-cache”); //for http 1.1 based servers

res. setHeader (“pragma”, “no-cache”); //for http 1.0 based servers

* Buffer is a temporary memory which stores the data for temporary period. Buffer is also called as cache.
