Exercise 11. Edit the Apache config file (or use a .htaccess file) and set the default expiration for cached documents to 1 hour after the document is first accessed. What directives and values did you use for this?2. Restart Apache and retrieve the ‘index.html’ file at http://localhost/index.html3. View the response headers ‘Expires’ and ‘Cache-Control’. What values do these headers have? Explain what these values mean.4. Edit the Apache config file (or use a .htacess file) and set the expiration time for text files to 30 minutes after the document was last modified. Set the expiration time for image files to 1 hour after the file was last accessed. What directives and values did you use for this?5. Restart Apache and view the response headers after requesting both an image and a text file.What values to you see in ‘Expires’ and ‘Cache-Control’ headers?6. Modify the text file and request it again. Now what values do you see in these headers? Is this what you expect? Why?Exercise 21. Configure Apache on your local host as a forward proxy server. What directives and values did you use?2. Configure a browser on a different host to use that Apache proxy server and verify that it works. Make a request to ‘http://apache.org’. Check the log files on your proxy server. Do you see any log entries?3. Configure your proxy server to block requests to ‘apache.org’ and try again to access it using your browser. Can you access it? What entries do you have in your proxy server log file?

Read through the whole project before beginning.  Based on the information provided below, you will be creating Database Design Language and Entity Relationship Diagram. Database Design Language (DBDL) Use Word to create the DBDL. When creating the DBDL, list out all relations in 3NF.  On each relation, create functional dependencies to make sure all relations are in 3NF!! Entity Relationship Diagram (ERD) An ERD is the visually representation of the database structure.  Draw the diagram for the scenario using LucidChart. When drawing the objects, be sure to use the correct shapes and syntax. List out all alternate keys, secondary keys, and foreign keys under the relation using the correct syntax.   An online movie database keeps tracks of information on movies, actors, directors, the genre of movies, and the characters portrayed by each actor in the movie.  The specific data requirements for the database is summarized as follows: Each movie is identified by a unique number.  Other information kept on each movie is the name of the movie, length of the movie, release date and parental rating. An actor is identified by a unique number, first name, last name, date of birth and gender.  A director is identified by a unique number, first name, last name, date of birth and gender. A character is identified by a unique number, first name, and last name.  A genre is identified by a unique number and the description of the genre. A Movie has multiple actors (or none at all). An Actor can play multiple roles in a movie. A character must be associated with a movie and an actor.  A character can be in multiple movies. (i.e. Sequels) A character can be portrayed by multiple actors in a movie. (i.e. Character in a movie has a younger and older version – two actors need to play the part). A Movie can have multiple directors (or none at all). A movie must have at least one genre (or could have many).
