Installing Web Access Gateway

The SanteDB web access gateway is a specialized dCDR instance which permits accessing SanteDB instances over the internet. The dCDR Web Access Gateway allows users with an internet connection and a web-browser to access SanteDB Applets.
Use cases for installing the Web Access Gateway include:
The centralized Administration Panel 
A centralized jurisdictional portal to an IMS interface
A centralized Audit Repository User Interface
The web access gateway is deployed in two steps:
1.Installing the Software Services 
2.Joining the central iCDR security domain
System Requirements
The minimum system requirements for installing the Web Access Gateway on a physical or virtual operating environment are as follows:
Microsoft Windows Server 2012 Standard, or
Ubuntu Linux 18.04 or equivalent distribution
2x CPU Cores (4x recommended)
2 GB RAM  (4 GB recommended)
100 MB of HDD space (1 GB recommended)
Installing Software Services
You can obtain the SanteDB Web Access Gateway software from the SanteDB WWW GitHub Project.
Installation of the Web Access Gateway should be performed on machines, containers, or VMs on the same physical network as the central iCDR server. Additionally, it is recommended that the iCDR and Web Access Gateway communicate on the protected, internal network over HTTP rather than HTTPS (to reduce the overhead of establishing SSL communications on an already physically secured network).
Installation on Microsoft Windows
Installation of the Web Access Gateway on Microsoft Windows Operating Systems is a standard Windows Installer experience. The application installer will copy the 
After installation is complete you will be asked to Configure the Web Access Gateway.
Upgrading Web Access Gateway Software on Windows
When updating the SanteDB Web Access Gateway, you should use the installer provided for the new version. The installers for the Web Access Gateway are able to restart services and perform partial upgrades of the program files installed. 
You may receive a notice to restart existing running services. It is safe to select Automatically Close Applications.

Using Docker Containers
You can use the santedb-www:latest Docker container to leverage the SanteDB web access gateway by adding a www container reference to your docker-compose.yml file and redirecting port 9200 to an appropriate outside port.

  www:
2
    image: santesuite/santedb-www:latest
3
    container_name: santedb-www

    ports:

    restart: always
Copied!
Once configured you can access the portal by navigating to : http://localhost:9200
Never expose the SanteDB WWW host container to the internet. If you are running the santedb-www container and wish to expose it to external clients, it is recommended you use SSL termination with either IIS or NGINX. See Securing SanteDB APIs​
Configure the Web Access Gateway
After installation is complete you can navigate to http://127.0.0.1:9200 in a support web browser (the Web Access Gateway is tested with Chrome, Firefox, and Microsoft Edge). 
The configuration screen for the web access gateway is identical to the configuration screen for the Disconnected Gateway, except the online mode is the only mode supported.
Join the Security Domain
Local Device ID: The device identifier which this web access gateway will use to enrol itself in the iCDR security domain (example: admin-portal or admin-portal-cluster-1)
Domain Address: The IP address or host name of the iCDR server instance. If you're running the iCDR in a distributed deployment, this should be the address to a machine or group running the Administrative Management Interface  .
Client Secret Mode: If you have configured the SanteDB OAUTH services (or are using a third party IdP) to use client secrets in the Authorization header , set this HTTP BASIC otherwise leave this as the default.
Application Secret Override: If your deployment has changed the default application secret for the application org.santedb.disconnected_client then you should set it here.
iCDR Administrative Port: The port where the SanteDB iCDR is listening for traffic
Use TLS/SSL: When communicating with a remote server, you should select this option.
Pressing the JOIN button will require you to login as the system administrator for the SanteDB server.
You should use the administrative user account and password to authenticate yourself with the domain.
Set Web Access Gateway Role
A single SanteDB iCDR server can host multiple SanteDB solutions and user interfaces. For example, an iCDR for SanteMPI may contain the SanteMPI administrative interface, an end-user registration interface, and a variety of other applications. 
When configuring the SanteDB Web Access Gateway (like all dCDR instances) you must select the application role that the SanteDB dCDR will be taking on.
Additionally, it is recommended that you select SanteDB to automatically update applets on the Web Access Gateway.  
The SanteDB dCDR software packages like the Windows Application, Android Application and dCDR Gateway may opt to not auto-update applets depending on bandwidth restrictions.
Set Synchronization Mode to Online
Since the SanteDB Web Access Gateway is intended to be used in an environment where it can always communicate with the iCDR server directly, and because it lacks the storage capacity to operate offline, the synchronization mode of the Web Access Gateway should be set to Online Only.
Set Log Verbosity
By default, SanteDB Web Access Gateway release builds will only log events which are errors or warnings. If you desire more verbose logging you can alter the setting for logging in this panel.
Application Services
It is recommended you leave the default application services selected for the Web Access Gateway. These settings are primarily intended for disconnected client gateways which require fine tuning of HL7, FHIR, ATNA and other services for local clinics.
Set Networking Parameters
By default, the SanteDB dCDR instances will optimize traffic with the central iCDR using one of BZIP, GZIP, deflate, or LZMA compression (depending on the network infrastructure). The network optimization panel allows you to tell SanteDB about the networking environment in which this dCDR instance is running.
If you're running the iCDR server on the same machine as the Web Access Gateway or are using a 10gbE connection between the two, you can set this to Local Network, since this will disable all compression (saving compute resources). If you are running the Web Access Gateway and iCDR in an environment which has a slower connection between the iCDR and dCDR it may be beneficial to select another option.

You may also optionally proxy traffic flowing between the Web Access Gateway and the iCDR instance by enabling the Use a proxy to access the server. This is useful if you're diagnosing performance bottlenecks between the systems, or the data center requires proxying.
Other Settings
The other settings panel allows you to configure custom behaviors for the Web Access Gateway. These settings are documented on the User Interface App Settingswiki page.
You can change the application settings for the Web Access Gateway after initial configuration via the file %systemroot%\Windows\SYSWOW64\config\systemprofile\AppData\Roaming\SanteDB\wwww-default on Windows or via ~/.config/santedb/santedb-www on Linux and Docker.
Restart Web Access Gateway
After the setup is complete you will be notified that your configuration has been saved and will wait for an application restart. This process typically takes between 10 and 20 seconds. The page should automatically refresh.
