A simple CGI script

The first task is to write a very simple perl program which just prints out an HTML document. This should include all the usual '' ... '' and ' commands. However, there are two things to note.(pl ingore '' sign)

First of all, the first two lines of the print out are special. The first line must be

Content-type: text/html

so that the browser knows what kind of document it is and therefore how to display it. In this case it is a text document of the subclass HTML. You can also send back plain ASCII documents by using text/plain instead. Sound samples and images also have to have the content type specified appropriately. The second line must be blank (ie it must contain just a line feed). This line is reserved for future development.

The second point is really a tip: Strings in perl programs can span over several lines. This means the main part of your perl program can just be one enormous print statement.
