The first time you open a 4D application that is built for the web, you will probably want to immediately go and check out the Database Properties. Again, this menu is available in the Design environment, under the File menu. Let us examine the Web Services settings for the Room4Rent application.
We see that this database has an "html" folder specified as the Default HTML Root. We also see that there is a Default Home Page called "index.html". Also, we can tell that this is a non-contextual application, since the "Non-contextual Mode" box is checked. Finally, you see that this database is not set to use any of 4D's built-in web password features.
It is also instructive to check out the second Web Services Settings page in Database Properties.
Under the options section note that the requests made to 4D's Web Server will be logged, saved in Common Log Format. At the top of the window, you can see that a Web Page Cache is being utilised. This is important to note, since if you change an HTML page that has already been sent through 4D's middleware engine, it will have been cached. To see any changes you have made, you will need to click this "Clear Cache" button. Alternatively,you can issue a special URL to 4D that will clear the cache: /4DCACHECLEAR.
