Configuration redirect ScadaBR to Scada‐LTS [Tomcat 9.0 Linux Windows]

From version v2.7.7 we do not support the ScadaBR address. To maintain compatibility with the old Address, in case of an old configuration, you need to configure a redirection in Tomcat.

To achieve this effect, we recommend using the valve mechanism available in Tomcat 9: https://tomcat.apache.org/tomcat-9.0-doc/rewrite.html and class RewriteValve: (if system Windows then change $CATALINA_HOME to %CATALINA_HOME%)

1. Stop tomcat;

2. Go to $CATALINA_HOME/webapps and rename ScadaBR.war to Scada-LTS.war and ScadaBR to Scada-LTS;

3. Create configuration file: $CATALINA_HOME/conf/Catalina/localhost/rewrite.config with content (syntax is similar to the Apache server configuration):

RewriteCond %{REQUEST_PATH}  ^/ScadaBR/.*$
RewriteRule ^/ScadaBR/(.*)$ /Scada-LTS/$1 [L,NE,R]

RewriteCond %{REQUEST_PATH}  ^/ScadaBR$
RewriteRule ^/ScadaBR$ /Scada-LTS [R]

Use flags:

• L (last) - if it matches the rule, it does not analyze the file further
• NE (no escape) - does not escape characters if the original url contained the following characters: "%", ";" etc
• R (redirect) - address as a "uri" and not as a "file system path"

4. In the file: $CATALINA_HOME/conf/server.xml In the tag: Server -> Engine -> Host Added:

<Valve className="org.apache.catalina.valves.rewrite.RewriteValve" />

5. Start tomcat and now I can use ScadaBR and Scada-LTS addresses (ScadaBR redirect to Scada-LTS);
