Why use url rewrite filter in spring?

Question

A Spring application that I use declares a Tuckey UrlReWrite Filter, and then sets the rewrite rule as follows:

<rule>
    <from>^/(.*)$</from>
    <to last="true">/app/$1</to>
</rule>

Why is this?

Could Spring be able to recognize requests that do not reach the URL /app/?

Otherwise, what is the advantage of this redirect?

, , Spring MVC DispatcherServlet URL- , URL- . <url-pattern>/</url-pattern>, .

, :

<urlrewrite default-match-type="wildcard">
    <rule>
        <from>/staticContentHere/**</from>
        <to>/staticContentHere/$1</to>
    </rule>
    <rule>
        <from>/**</from>
        <to>/app/$1</to>
    </rule>    
</urlrewrite>
