Abstract

A method, apparatus, and computer program product are provided for providing a local proxy for accessing web services. An apparatus may include a processor configured to receive, at a proxy service implemented on the apparatus, a first HTTP request from a HTTP protocol client application executed on the apparatus. The first HTTP request may be directed to a first network location, wherein the HTTP client application is associated with the first network location. The processor may be further configured to determine whether the first HTTP request includes an indication of a second network location for circumventing a same-origin policy. The processor may additionally be configured to transmit a second HTTP request to the second network location when the first HTTP request includes an indication of a second network location. Corresponding methods and computer program products are also provided.

determine whether the first transfer protocol request includes an indication of a second network location for circumventing a same-origin policy; and

transmit a second transfer protocol request to the second network location when the first transfer protocol request includes an indication of a second network location.

2. An apparatus according to claim 1, wherein the processor is further configured to:

receive a first transfer protocol response to the second transfer protocol request;

transmit, to the transfer protocol client application, the second transfer protocol response in response to the first transfer protocol request.

3. An apparatus according to claim 1, wherein the processor is configured to determine whether the first transfer protocol request includes an indication of a second network location by determining whether the first transfer protocol request includes a transfer protocol header including an indication of a second network location.

4. An apparatus according to claim 1, wherein the transfer protocol client application comprises a mashup application.

5. An apparatus according to claim 4, wherein the mashup application is executed within an application runtime that enforces same-origin policy.

6. An apparatus according to claim 1, wherein the second network location is associated with a local content server embodied on the apparatus;

and

wherein the processor is configured to transmit a second transfer protocol request to the second network location by transmitting a second transfer protocol request to the local content server.

7. An apparatus according to claim 6, wherein the local content server provides context information related to one or more of the apparatus or a user of the apparatus.

8. An apparatus according to claim 1, wherein the processor is further configured to:

determine, when the first transfer protocol request includes an indication of a second network location, based at least in part upon a set of access rules stored in a local memory whether a stored access rule governs the first transfer protocol request; and

determine, when a stored access rule governs the first transfer protocol request, whether the stored access rule allows a transfer protocol client application associated with the first network location to transmit transfer protocol requests to the second network location; and

wherein the processor is configured to transmit a second transfer protocol request to the second network location by transmitting a second transfer protocol request to the second network location when a stored access rule governs the first transfer protocol request and allows a transfer protocol client application associated with the first network location to transmit transfer protocol requests to the second network location.

9. An apparatus according to claim 8, wherein no stored access rule governs the first transfer protocol request;

and wherein the processor is further configured to;

prompt a user of the apparatus to select a security permission option for the first transfer protocol request from a plurality of selectable security permission options;

receive an indication of a selected security permission option for the first transfer protocol request; and

determine whether the selected security permission option allows the transfer protocol client application to transmit a transfer protocol to the second network location; and

wherein the processor is configured to transmit a second transfer protocol request to the second network location by transmitting a second transfer protocol request to the second network location when the selected security permission option allows the transfer protocol client application to transmit a transfer protocol request to the second network location

10. An apparatus according to claim 9, wherein the processor is configured to:

generate an access rule based at least in part upon the selected security permission option; and

update the set of access rules to include the generated access rule.

11. A method comprising:

receiving, at a proxy service implemented on a computing device, a first transfer protocol request from a transfer protocol client application executed on the computing device, wherein the first transfer protocol request is directed to a first network location, and wherein the transfer protocol client application is associated with the first network location;

determining whether the first transfer protocol request includes an indication of a second network location for circumventing a same-origin policy; and

transmitting a second transfer protocol request to the second network location when the first transfer protocol request includes an indication of a second network location.

12. A method according to claim 11, further comprising:

receiving a first transfer protocol response to the second transfer protocol request;

generating a second transfer protocol response based at least in part upon the first transfer protocol request and the first transfer protocol response; and

transmitting, to the transfer protocol client application, the second transfer protocol response in response to the first transfer protocol request.

13. A method according to claim 11, wherein determining whether the first transfer protocol request includes an indication of a second network location comprises determining whether the first transfer protocol request includes a transfer protocol header including an indication of a second network location.

14. A method according to claim 11, further comprising:

determining, when the first transfer protocol request includes an indication of a second network location, based at least in part upon a set of access rules stored in a local memory whether a stored access rule governs the first transfer protocol request; and

determining, when a stored access rule governs the first transfer protocol request, whether the stored access rule allows a transfer protocol client application associated with the first network location to transmit transfer protocol requests to the second network location; and
