Windows host files <ul><li>In Windows, host files can be used to provide similar functionality to DNS servers. </li></ul><ul><li>It is practical only for very small networks </li></ul><ul><li>Edit the files in the directory: c:windowssystem32driversetc </li></ul><ul><li>Two files are of interest host – from IP to web based name lmhost – from IP to NetBui name </li></ul>
  2. 2. How a Web Server Works <ul><li>As is true with other servers such as DNS, Web servers listen for communication at a port </li></ul><ul><ul><li>The default port is 80 </li></ul></ul><ul><ul><li>You can also create Web servers at port numbers greater than 1023 </li></ul></ul><ul><li>Each Web server has a root, which is where you store the HTML documents </li></ul>
  3. 3. Understanding HTTP <ul><li>The current version of HTTP is 1.1 </li></ul><ul><ul><li>Virtually no browsers are so old that they do not support 1.1 </li></ul></ul><ul><li>HTTP is a stateless protocol, meaning that each Web page sent is independent of every other Web page sent </li></ul><ul><ul><li>This makes it more challenging to create a shopping cart application </li></ul></ul>
  4. 4. Understanding HTTP <ul><li>HTTP 1.1 supports persistent connections </li></ul><ul><ul><li>This allows the browser to receive multiple files in one TCP connection </li></ul></ul><ul><ul><li>This can speed up communication </li></ul></ul><ul><ul><li>Although you see a single page in your browser, it can be composed of many text and image files </li></ul></ul>

  6. 6. Understanding HTTP <ul><li>The following shows some of the headers along with the HTML that the Web server would send: </li></ul><ul><li>HTTP/1.1 200 OK </li></ul><ul><li>Server: Microsoft-IIS/5.0 </li></ul><ul><li>Content-Type: text/html </li></ul><ul><li>Last-Modified: Fri, 17 May 2005 18:21:25 GMT </li></ul><ul><li>Content-Length: 43 </li></ul><ul><li><html><body> </li></ul><ul><li>Hello, World </li></ul><ul><li></body></html> </li></ul><ul><li>The headers contain information about the page </li></ul>
  7. 7. Features in IIS <ul><li>IIS versions associated with Windows versions </li></ul><ul><ul><li>Windows NT – IIS 4.0 </li></ul></ul><ul><ul><li>Windows 2000 – IIS 5.0 </li></ul></ul><ul><ul><li>Windows Server 2003 – IIS 6.0 </li></ul></ul><ul><li>SMTP can be easily added so you can send e-mail from your Web pages </li></ul>
  8. 8. Features in IIS 5.0 <ul><li>Web Distributed Authoring and Versioning (WebDAV) </li></ul><ul><ul><li>Allows a server to share Web-based files </li></ul></ul><ul><li>Named virtual hosting </li></ul><ul><ul><li>Multiple Web sites can share a single IP address </li></ul></ul><ul><li>Per Web site bandwidth throttling </li></ul><ul><ul><li>Control bandwidth by Web site </li></ul></ul><ul><li>Kerberos authentication </li></ul><ul><li>Secure Sockets Layer 3.0 </li></ul><ul><ul><li>Encrypted communication </li></ul></ul>
  9. 9. Features in IIS 6.0 <ul><li>Increased security </li></ul><ul><ul><li>Default permits only HTML documents </li></ul></ul><ul><li>Expanded language support </li></ul><ul><ul><li>Can use XML and SOAP </li></ul></ul><ul><li>Support for IPv6 </li></ul><ul><li>Increased dependability </li></ul><ul><ul><li>Kernel-mode HTTP service </li></ul></ul><ul><ul><li>Self-healing mechanism </li></ul></ul>
  10. 10. Components in IIS <ul><li>File Transfer Protocol (FTP) server </li></ul><ul><ul><li>To transfer files between user and server </li></ul></ul><ul><li>FrontPage 2000 Server Extensions </li></ul><ul><ul><li>Used by programs to transfer files to and from a Web site </li></ul></ul><ul><li>NNTP Service </li></ul><ul><ul><li>Used to create user forums </li></ul></ul><ul><li>SMTP Service </li></ul><ul><li>World Wide Web Server </li></ul>

  12. 12. Tabs on the Default Web Site Properties Dialog Box <ul><li>Operators (Windows 2000) only </li></ul><ul><ul><li>This property lists users who can administer Web site </li></ul></ul><ul><li>Performance </li></ul><ul><ul><li>Limit bandwidth by Web site </li></ul></ul><ul><ul><li>Limit simultaneous connections (Windows 2003) </li></ul></ul><ul><li>ISAPI Filters </li></ul><ul><ul><li>Specify applications that process HTTP requests </li></ul></ul>
