What is CGI ?

Common Gateway Interface or CGI is a program that can interact with an html form on your web site, and processesrepparttar 134396 results on your server using a cgi script. The result generated is a dynamic web page. The cgi script is written in a language called PERL ("practical extraction and reporting language").

Uses of CGI scripts

CGI scripts are most commonly used for creating user interaction with a html form on your web site. Other uses include: autoresponders, shopping carts, counters, mailing list managers, ad management, surveys, polls, discussion boards, content management, calendars and click tracking.

Article available for reprint: ==================================================== Hosting of web sites has essentially become a commodity. There is very little distinguishing one hosting company fromrepparttar 134397 next. Core plans and features arerepparttar 134398 same and price is no longer a true determining feature. In fact, choosing a host based onrepparttar 134399 cheapest price can be more expensive inrepparttar 134400 long term with respect to reliability issues and possible loss of sales as a result of website downtime.

Selecting a host fromrepparttar 134401 thousands of providers and resellers can be a very daunting task, which may result in a hit and miss approach. But although hosting may have become a commodity, one distinguishing feature that you must always look out for is reliability.

Atrepparttar 134402 heart of any hosting company's reliability is redundancy. This ensures that if a problem exists at one point, there will be an alternative which ensures continuity as seemlessly and transparently as possible.

Most hosts do employ redundant network connections. These arerepparttar 134403 high speed pipes that route data fromrepparttar 134404 server to your web browser. But, redundant 'multiple web servers' have been extremely rare and very expensive, requiring costly routing equipment which has previously been used only in mission critical applications of Fortune 500 companies.

However, a very neat but little known Domain Name Server(DNS) feature called 'round robin' allowsrepparttar 134405 selection and provision of a particular IP address from a 'pool' of addresses when a DNS request arrives.

To understand what this has to do with server reliability it's important to remember thatrepparttar 134406 Domain Name Server (DNS) database maps a host name to their IP address. So instead of using a hard to remember series of numbers (IP address) we just type in your web browser, to get to your website.

Now, typically it takes at at least 2 to 3 days to propagate or ‘spreadrepparttar 134407 word’ of your DNS info throughoutrepparttar 134408 internet. That's why when you register or transfer a domain name it isn't immediately available torepparttar 134409 person browsingrepparttar 134410 web.

This delay has stymiedrepparttar 134411 security benefits of hosting your site on multiple servers, as your site would be down for a couple of days if something went awry with one server. You would have to change your DNS to reflect your second server and wait days beforerepparttar 134412 change was picked up in routers onrepparttar 134413 internet.
