Hi,<br />
I'm writing perl CGI programs that will run a Web site. &nbsp;On one page, if the user clicks on a link, he initiates some processing, and he'll be taken to another page. &nbsp;The processing will read data from a couple other Web sites, process the data, and send email to the user. &nbsp;But there's no reason the user should have to wait for all that to happen before being sent to the next page for him to view. &nbsp;The processing could happen in the background, so to speak.<br />
<br />
I'd like to find a way for the program that initiates the processing to continue, sending the user to his new page, without waiting for the processing to finish. &nbsp;Is there a way to do that?<br />
Thanks,<br />

Want my perl CGI program to continue without waiting for return from a subroutine

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
