A computer implemented method provides a web service to a client. A document request identifying a web service on a web service server is sent from the client to an application server. The document request is stored at a first location. The application server then sends a proxy document request back to the client, wherein the proxy document request identifies the first location. The client then forwards the proxy document request to a web service. The web service generates a web service response, by resolving the proxy document request to the first location. The web service response is stored at a second location. A proxy web service response can then sent from the web service back to the client, wherein the proxy web service response identifies the second location. The client then forwards the proxy web service response to the application server. The application server generates a document response, by resolving the proxy web service response to the second location. The application server then forwards the document response to the client.
