Service Proxy for Web Service Authentication and Request Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The server to server approach as a backup to client to server web service implementation is difficult to maintain due to the need for extensive code modifications across email clients and email servers, making deployment and updates time-consuming and prone to errors when configuration parameters of the web service change.
Innovation Solution
Deploying a service proxy on an intermediate server that authenticates clients and servers, allowing requests to be forwarded directly to the target server without processing, thus enabling fast and efficient updates by only modifying client-side code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If server to server approach is implemented as backup to client to server web service implementation, then reliability is improved, but device complexity and ease of operation deteriorate due to extensive code modifications needed across email clients and email servers
Solution Approach 1:
The patent introduces an email server as an intermediary component that mediates between the client device and the file server. The email server includes a service proxy that forwards requests from the client to the file server, eliminating the need for direct server-to-server authentication and code modifications. This intermediary approach maintains reliability while reducing system complexity.
2Reliability
If server to server approach is implemented as backup to client to server web service implementation, then reliability is improved, but ease of operation deteriorates due to extensive code modifications needed across email clients and email servers
Solution Approach 1:
The email server acts as a mediator that simplifies the interaction between client and file server. By implementing a service proxy on the email server, the system enables automatic request forwarding without requiring complex code modifications on client devices or file servers, thus improving ease of operation while maintaining reliability.
3Reliability
If extensive code modifications are made across email clients and email servers to implement server to server approach, then reliability is improved, but productivity deteriorates due to time-consuming deployment and updates
Solution Approach 1:
The service proxy implemented on the email server as an intermediary eliminates the need for synchronized code updates across multiple systems. The proxy handles request forwarding and authentication centrally, allowing independent deployment and updates of email clients and file servers without compromising reliability, thus significantly improving productivity.
4Reliability
If extensive code modifications are made across email clients and email servers to implement server to server approach, then reliability is improved, but ease of manufacture deteriorates due to time-consuming deployment and updates
Solution Approach 1:
By positioning the service proxy on the email server as an intermediary, the system decouples the deployment processes of different components. The email server's service proxy handles the complex authentication and forwarding logic centrally, making the system easier to manufacture and deploy without requiring coordinated code changes across multiple systems, while maintaining reliability.

AI summary
Techniques to handle calls to web services via a service proxy are disclosed herein. In one embodiment, a technique includes an intermediate server receiving a request from a client device to the web service at a target server. In response to receiving the request, the intermediate server can authenticate the received request from the client device and upon successful authentication of the received request, forward the request to the targeted server and invoking the web service to process the forwarded request because the intermediate server is authenticated with the target server. The technique can also include receiving, at the intermediate server, data from the target server that represents execution results of the request by the web service at the target server. Upon receiving the data, the intermediate server can then forward to the client device, the data representing execution results of the request by the web service at the target server.
