  3. htaccess SEO and Security Tips This is a beginner's guide to htaccess. It is meant to introduce this configuration file and its useful implementations in website management. .htaccess is a server configuration file commonly found in Apache, Zeus and Sun Java System web servers. It provides a lot of applications with implications for website security and search engine optimization. You cannot find or use .htaccess in Microsoft-based IIS servers and non-Apache-based servers.To create and upload an htaccess file: 1. Open any text editor (such as geditor in Ubuntu or notepad in Windows). 2. Enter the htaccess syntax you would like to implement on your website (at the text file). 3. Save it as .htaccess Note: There is a "." before the filename, and there is no file extension to it; just .htaccess 4. Upload it to a directory where you would like the directives to be implemented. An htaccess uploaded to the root directory of your website will cover all of the website's directories and files (from root to inner). But if you upload only the .htaccess file to a specific inner directory, the directives on that .htaccess file can be only be implemented in that specific directory. IMPORTANT: If you have an existing .htaccess in your website and you plan to edit it, it is extremely important to secure a backup of that .htaccess first, before doing anything else. 301 redirecting old/dead URL to new URL Suppose you have URLs, and then you delete them because they are no longer needed. You need to replace them with new URLs (by re-publishing content, for example, or shortening your URLs). With respect to SEO implementation, this approach can cause you to lose a lot of traffic and link juice, because those old URLs might be contributing a very significant amount of traffic and links to your website. What is the best solution? Instead of giving those URLs a 404 header status (not found, or does not anymore exist), you need to 301 redirect those non-existing URLs to their new, permanent location. With this method, if those dead URLs are still indexed by Google, any users coming from search engines or other websites can still read and visit the new URLs because they have been "301 redirected." To do this, you can use .htaccess to do the 301 redirects. For example: HTACCESS SYNTAX: redirect 301 /2009/04/how-to-make-blogger-post-title-unique.html http://www.php-devel...t-title-unique/ redirect 301 /about/ http://www.php-devel...g/about-codexm/ There are two 301 redirection commands above; the first is to 301 redirect: http://www.php-devel...tle-unique.html TO: http://www.php-devel...t-title-unique/ The second redirection is to 301 redirect: http://www.php-developer.org/about/ TO: http://www.php-devel...g/about-codexm/ What if you have a URL with spaces? For example: http://www.php-devel...tutorials/Excel database functions sample sheets.xls Then you will need to use a double quote in the 301 redirection line, e.g: HTACCESS SYNTAX: redirect 301 "/wp-content/uploads/tutorials/Excel database functions sample sheets.xls" http://www.php-devel...-sample-sheets/ The above line will 301 redirect that URL with spaces to this new location: http://www.php-devel...-sample-sheets/ Note: 301 redirection implementations using .htaccess will be uploaded to the root directory of your website. If you have an existing .htaccess, you will simply need to edit it and add the redirection lines. You will not need to actually create a brand-new .htaccess. Disable hot linking to save website bandwidth If you have a website in which you are hosting fairly large files like MP3s, video files and audio wave files, then someone outside your domain might be tempted to take advantage of your website's resources by directly streaming/linking to it, without paying a single penny for bandwidth use. Why is this not good? Your website's bandwidth (for which you are paying with your hosting bills) is being substantially consumed by unauthorized persons. This is known as "bandwidth theft" and includes stealing pictures from your website by reusing them in another website (NOT in your website). Abuse can slow down your site and weaken your website security. This is where you can use .htaccess to prevent this. For example, say you want to prevent "hot linking" for the following file types mp3, jpg and wav audio files. You want to allow only your own domain (e.g yourdomain.org) to access them; other domains are restricted. HTACCESS SYNTAX: ## DISABLE HOTLINKING RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www.)?yourdomain.org/.*$ [NC] RewriteRule .(mp3|jpg|wav)$ - [F] Again, if you upload the .htaccess file to the root directory of your website, all of your website directories and files will be protected against hot linking, as stated in your .htaccess file. Adding more than one domain to hot link to your site There are times when you have several websites and you need to hotlink to the images, perhaps for convenience and saving disk space. In this case, if you implemented the above .htaccess syntax, then your website will not be permitted to access those images. You can grant permission to any website to access and "hot link" your web content (images, etc). For example: HTACCESS SYNTAX: ## DISABLE HOTLINKING RewriteEngine on # Options +FollowSymlinks RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www.)?yourdomain.org/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://(www.)?seochat.com/.*$ [NC] RewriteRule .(mp3|jpg|wav)$ - [F] The .htaccess lines above allow seochat.com to hot link to yourdomain.org website (in addition to yourdomain.org, of course).

  4. Internet Cafe Security Tips The majority of Internet cafes worldwide use Windows-based operating systems, which are subject to massive malware/virus and security-related attacks. Still, many users are not fully aware of the danger of surfing the web in an Internet cafe. This article will explain the dangers, and show you how to surf the Internet safely from an Internet cafe. There are two basic dangers that one must be aware of when using an Internet cafe. First, lots of these Internet cafes do not offer much protection in the way of user privacy. This means they have inadequate firewalls and real-time antivirus software. As a result, any active malware, such as a Trojan, can steal a lot of personal information from you, including your user login and password. Second, Internet cafes sometimes use third party software or hardware to intercept packets (using an eavesdropping technique). This, again, can lead to abuse. Particularly if personal data is collected, such data can be used to steal your online identity. This tutorial will guide beginning users of Internet cafes in how to increase the level of online protection, in such a way that using them can be as safe as possible. Bear in mind that, although this tutorial will do its best to protect online users of public Internet cafes, nothing is entirely safe when using public computers and the Internet. For complete privacy and protection, you are advised to use your own computer/laptop, as well as a network which you have full confidence in its being secure. Basic Preparation: Encrypt Data on Your Own USB Flash Drive One of the first things you need to secure before you use an Internet cafe is your own USB Flash drive. Bring this along, as this will be used to store your files when you are using an Internet cafe. Of course you need to protect your files and data inside the USB flash drive. A good rule is to always encrypt the file that contains a password. Suppose you have a notepad file that consists of a long list of usernames and passwords of different websites; a common mistake is to leave it in the form of a .txt file and save it on a USB flash drive. Some malware scripts are programmed to scan these types of files and harvest passwords. So you need to ensure that you are protecting your sensitive data from being read and accessed. The best tool that can offer protection to this kind of file, such as encryption, is Keepas. This tool is free. Once you download the classic edition, follow these steps to use it: 1. Right click on the downloaded file (e.g. KeePass-1.18) and then unzip the archive. 2. This will extract the folder named, for example, KeePass-1.18. The screen shot below shows you what the contents of this folder should be: 3. In the folder, double click Keepas.exe then go to File -> New. 4. Now type a master password, something that is easy to remember but not too simple. 5. Check "Use master password and key file." 6. Under "Key File," select C: pwsafe.key, assuming that your main Windows hard drive is drive C. Click OK. Important: For security reasons, it is recommended that you use a unique key file, not just the default Keepas provided key file. You can use any key file you like; please refer to Keepas documentation for details. 7. Type the "master password" again; enter the same password you used in step 5, and then click OK. 8. Under "Get Random data for key generation," click "User Mouse as Random source," and then move your mouse until the bar field is full. Click OK. 9. Go to Edit -> Add Entry. Go ahead and type all username/password entry combinations that you are going to use when you are in the Internet caf
