               <p>One way for applications to practically bypass this limitation in some situations is by using a trusted or preferred proxy. An application can discover a resource's advertised proxy via the <code>solid:proxy</code> property. While any resource, such as a storage, could advertise a proxy, applications can also discover an agent's preferred proxy by checking this property in their WebID Profile Document.</p>
 
               <p>Additionally, using a proxy allows applications to mask their <code>Origin</code>, enhancing privacy and security during requests. This capability can further protect user data in decentralised environments, though it may not fully address all related challenges on its own.</p>
