Web (Click and script) : Web(click and script ) has three types of recording options

GUI based

HTML based

URL based

Web (Click and Script) Vusers support non-HTML code such as Javascript on the client side. Web (Click and Script) Vusers handle most correlations automatically, reducing the scripting time.

What is correlation? Explain the difference between automatic correlation and manual correlation?

Correlation is used to obtain data which are unique for each run of the script and which are generated by nested queries. Correlation provides the value to avoid errors arising out of duplicate values and also optimizing the code (to avoid nested queries).

Automatic correlation is where we set some rules for correlation. It can be application server specific. Here values are replaced by data which are created by these rules. In manual correlation, the value we want to correlate is scanned and create correlation is used to correlate.
