Installing and Setting Up Web Application Back End

Installing of web application back end depends on the web server, on which it is installed:

Apache2 (Apache HTTP Server). It is available only in Linux OS.
ASP.NET (Internet Information Services). It is available only in Windows OS.
Java (Apache Tomcat).

Basic settings of the installed web application are determined in the PP.xml and config.json configuration files. After installing the back end, the general scheme of interaction between the web application and other system components looks as follows:

On the first addressing the web server from the browser, the required web application files and the login page for user authorization are downloaded to the client computer. The web application reads settings from the PP.xml and config.json configuration files.
The further operation mode depends on the read settings:

If the <service> section is set, the web application and BI server interact by direct queries to BI server via the PP.SOM.Som access point. The web server is addressed only if it is required to download some web application files.
If the <proxy> section is specified, all queries are sent to PPService.axd and then are redirected to the BI server. Take into account the features determined by a type of web server in use.

Query redirection can also be configured directly on the web servers, which is used after the web application backend has handled queries.

TIP. To access the web application, see the Opening Web Application article.
