Data communication in a clustered data processing environment

A computer-implemented method for communicating data in a clustered data processing environment, the method comprising:

• receiving, at a server in the clustered data processing environment, a request and a token from a web user interface (UI) component, the token created during storing of a data object in a local cache, wherein the data object comprises a set of credentials, and wherein the token includes a specific configuration, credential, and referenced server;
• searching, based on the token and for the data object, the local cache, wherein the data object comprises a set of backend response configurations and wherein the backend response configurations are unique to a particular user of the web UI component;
• detecting, in response to the searching, the data object in the local cache;
• communicating, using the data object, with a backend server;
• receiving, from the backend server and in response to the request, server-specific data;
• returning, to the web UI component, based on the server-specific data from the backend server and data held in the data object, a response, wherein the response is formulated based on a set of data defined in the data object;
• receiving, at the server in the clustered data processing environment, a second request and a second token from a second web UI component, the second token created during storing of a second data object in another local cache on another server in the clustered data environment;
• searching, based on the second token and for the second data object, the local cache;
• detecting, in response to the searching based on the second token and for the second data object, an absence of the second data object in the local cache;
• locating, in response to the detecting the absence of the second data object and in a dynamic cache, a byte array for the second data object, the byte array created during the storing of the second data object in the dynamic cache;
• rebuilding, based on the byte array for the second data object, the second data object;
• storing, in the local cache, the rebuilt second data object;
• communicating, using the second data object, with the backend server;
• receiving, from the backend server and in response to the second request, server-specific data;
• returning, to the second web UI component, based on the server-specific data from the backend server and data held in the second data object, a second response;
• determining the token is no longer required;
• and
• deleting the token created during the storing of the data object.
