When you see both domains, you have successfully used name-based virtual hosting with the Apache server. You may want to see the internal details of how the result appeared as expected. Here is a step by step summary of what happens when a user wants to see the www.pvctoyfan.com site using our Apache server enabled for virtual hosting: 1. 2. 3. 4. Using an HTTP/1.1 browser, the site visitor sends a request for http://www.pvctoyfan.com to our Apache server. The Apache server accepts the request and tries to find the Host header. It does, and the header contains www.pvctoyfan.com. Our server then checks whether the NameVirtualHost directive is enabled. It is, and Apache starts to search for each VirtualHost container. It starts with the first VirtualHost container (the one that contains the ServerName directive ServerName www.pvctoyfan.com). It tries to match the hostname from the Host header to the ServerName directive, and it matches. After the match, the Apache server prepares the required response by using the contents of the chosen VirtualHost container, and it gives it back to the requesting client. java upc-a Generate UPC-A barcode in Java class using Java UPC-A ...

The configuration for the default implementation is: <barcode> < upc-a > <height>{ length:15mm}</height> <module-width>{length:0.33mm}</module-width> ... Earlier, you saw this kind of trivial select clause collapsing away to nothing. However, that doesn t happen here, because this is what s called a degenerate query it contains nothing but a trivial projection. (Example 8-2 was different, because it contained a where clause in addition to the trivial select.) LINQ never reduces a query down to nothing at all, so when faced with a degenerate query, it leaves the trivial select in place, even though it appears to have nothing to do. So Example 8-18 becomes a call to the Select LINQ operator method: var projected = events.Select(ev => ev); java upc-a Java UPC-A Generator | Barcode UPCA Generation in Java Class ...

Java UPC-A Barcodes Generator for Java, J2EE, JasperReports - Download as PDF File (.pdf), Text File (.txt) or read online. PHP is one of the most important open source scripting languages available. It can generate web pages similar to CGI and has extensive libraries and add-ons that can be used in creating applications. The latter attribute has made it popular with web developers. PHP has support for regular expressions that you can use to filter user input and can connect with major databases such as PostgreSQL and MySQL. With PHP integrated in Apache, web developers can create robust online applications that do things rather than just show things. This will also complete your Linux-Apache-Middleware-Programming setup (LAMP) for web development. In this section, we will install PHP and enable it on our Apache server by loading it as a module. 1. Install PHP with PostgreSQL and MySQL database support to the system with the following command: yum install php php-pgsql php-mysql 2. Find the directive DirectoryIndex in the main section of the httpd.conf file and change it to DirectoryIndex index.html index.html.var index.php You ve added index.php as a starter page, and that page will be used if it is on the web directory. Save the file and reload the server using service httpd restart. 3. Create a test file called welcome.php inside the default document root directory of the www.pvctoyfan.com domain (/var/tmp/pvctoyfan/html) and give it the code shown in Listing 13-8. But projections often have work to do. For example, if we want to pick out event titles, we can write this: var projected = from ev in events select ev.Title; Again, this becomes a call to the Select LINQ operator method, with a slightly more interesting projection lambda: Listing 13-8. A Sample PHP Script < php print "We are now PHP-enabled."; > Save the file afterwards. 4. Type http://www.pvctoyfan.com/welcome.php in the address bar and the result should appear as in Figure 13-8. var projected = events.Select(ev => ev.Title); We can also calculate new values in the select clause. This calculates the end time of the events: var projected = from ev in events select ev.StartTime + ev.Duration; Figure 13-8. Your first PHP script running on the www.pvctoyfan .com domain You can now start PHP scripts in your Apache web server. If you need database connectivity with PHP using PostgreSQL and MySQL, it is already included and all you need to do is to use the proper functions for each database. You can learn more about PHP and its database programming libraries at http://www.php.net. You can use any expression you like in the select clause. In fact, there s not even any obligation to use the range variable, although it s likely to be a bit of a waste of time to construct a query against a data source if you ultimately don t use any data from that source. But C# doesn t care any expression is allowed. The following slightly silly code generates one random number for each event, in a way that is entirely unrelated to the event in question: In the chapter so far, all of our HTTP requests and responses have been sent in the clear. That approach is prone to cracker attacks such as sniffing, and transferring sensitive data can be hazardous. To complete this chapter you will apply what you have learned to create OpenSSL certificates here in Apache that will wrap your information through encryption. Random r = new Random(); var projected = from ev in events select r.Next(); java upc-a BE THE CODER > Barcodes > Barcode4j Examples > Barcode UPC-A
