3. Android Webserver Architecture

   Figure: 1 Basic Architecture of the Android Cloud Webserver

   Figure: 2 Operations and function involved in Android Cloud Webserver

   The android webserver can run a lots of variety of content management system such as like WordPress web application, Joomla Web application, Drupal Web Application, Prestashop Web application, etc. and beside Content management system it can also run the PHP frameworks such as like the Code Igniter

   application, YII developer application, CakePHP application, etc. It is same as the IIS-Internet Information Services, APACHE for Linux or such as like WAMP Server or the LAMP Server or the XAMPP Server running on the personal computer or personal laptops or netbooks, Standalone Servers etc. But this package is only built for the smartphone or android devices enabled with the lighttpd extensions like other Cloud Webservers.

4. Functionalities & Features

   • Features Server Side Includes (SSI):

     When you fill the variables, the text file it will also be replaced with corresponding to the content when someone or the other requests in the file is made. This works for the text files as mentioned below.

     {{include=(URL/Absolute mpath/Relative mpath)}}

     {{filemodified=(Absolute mpath/Relative mpath)}}

     {{filemodifiedstring=(Absolute mpath/Relative mpath)}}

     {{filesize=(Absolute mpath/Relative mpath)}}

     {{filesizestring=(Absolute mpath/Relative mpath)}}

     {{var=()}}

     • Root privileges is not needed:

       The application is a web application which runs on the web server without root privileges for the android includes:

     • Storage Engine supports Android Cloud Webserver with MySQL is as follows:

       • MyISAM

       • MRG_MYISAM

       • BLACKHOLE

       • CSV

       • MEMORY

       • INNODB

       • ARCHIVE

     • Syntax for the Configuration files

     The httpd configuration files contain the one directives per single line and the backslash "\" may also be used as one of the last character on the same line in order to indicate the directives which continues on the next line of the code statement. There must not be any other characters with the white space between backslash and at the end of the statement code line. The arguments of the directives are differently separated by the more number of whitespaces. If the argument contains the white spaces, we must enclose the argument in the double quotes of the code lines of the statement.

     Directives in httpd configuration files is case insensitive, but the arguments of the directives are most often used as case sensitive lines. The lines which begins with the hash character # is considered as the comments and they are automatically ignored. The comments may include the one line after the other with a configuration directives in the httpd file. The blank line and the white spaces is occurring

     before the directive which are ignored earlier, so that indent of the directives may go for the clarity.

     The different values of the multiple variables is also defined as the keyword define in the shell environment variables which can also be used in the various configuration file code statement lines using syntax ${VAR} and the "VAR" file is the archived and name of the valid variable in the value of that variable which is substituted into the spot of the configuration file in a command code line and the processing that continues as that, the text is found directly in the current httpd configuration file.

     The variables is defined as to take precedence in all over the shell environment with the multiple variables.

5. Conclusion

   Android smartphone as a Cloud Webserver is a HTTP server written in the PHP language based webserver and its open source package supports android smartphone devices with any android OS which can be installed into a smartphone with the help of .apk file. It is designed to be more secure, reliable and the extensible. It is being written in the PHP which it makes more easily extensible with the customized modules, more secure because the running inside off the Zend API scripting engine in order to immune the total number of the various common security threats such as the format strings and the buffer overflows etc. It can be used as the framework to develop and customize the standalone web based applications or frameworks. The Webserver with LiteHTTP Server that provides a wide variety of the different mechanisms in logging into the webserver from the initial requests through URL mapping process for the final resolution of the connection that also including any errors that it may have occurred in the current process. In addition to it the third party modules provides the logging capabilities in order to inject the entries into the current existing log file and the web applications like CGI programs or or PHP scripts and the other handlers may also send the messages to the server error logs in the cloud webserver.
