I wouldn't worry too much about this. It's an instruction to the browser telling it what character set is being used to construct the page, in this case the 191 character Latin alphabet. Wikipedia will tell you more about this. You can also run a search for Meta tags in HTML, which will provide you with a bit more information on what they are and why they are present.	[reply]

That's what you should get. If you run your script as a CGI script, it is necessary for that line to be there. It won't appear in the browser. If it does, you're not running your script as a CGI script, so you have a server configuration issue.	[reply]

What ikegami said is correct. Running the script from the command line will display the Content-Type line. When you run the script in a web browser that line is used by the browser to know what type of content it should display, i.e. text/html, and the rest of the output renders in this format. So everything is working alright :) You can alter the Content-Type (using the header_add or header_props methods of CGI::Application) to other kinds, e.g. application/pdf or text/csv or whatever you like, and your web browser will react accordingly, i.e. either render the output in the browser, or ask you to save the file, or launch the application used to view that kind of file. Because the default Content-Type is text/html your web browser displays the subsequent output as a web page. Here's one page that lists a lot of Content Types (also known as MIME Types): http://www.w3schools.com/media/media_mimeref.asp	[reply]
