CGI vs Servlets

[Raja Siva Ganesh Panuganti]

Plzz let me know the major difference between servlets and CGI
plz tell me abut their pros and cons
THANKS IN ADVANCE

[Colin Shine]

Servlets have far better scalability and performance, because each request is handled with a lightweight thread instead of spawning a new process.

Raja Siva Ganesh Panuganti, JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "plz" instead of spelling out "please" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.

Please read this for more information.

thanks,

The diff btw cgi and the servlets.

Cgi loads every time when a request comes..but in case of sertlets the controller loads on only 1 time at the time of the first request...and then just create an new thread...so cgi is slower then servlets..but at the first time when the servlets loads is slow...there is less secuirty in cgi then servlets...
