identifying, based on the web services request, at least two remote servers of a plurality of remote servers that are to fulfill at least a portion of the request; generating a first send web service request to be sent to a first remote server of the at least two remote servers, wherein the first send web service request comprises a first product identification information corresponding to a first product identified from the web service request; generating a second send web service request to be sent to a second remote server of the at least two remote servers, wherein the second send web service request comprises a second product identification information corresponding to a second product identified from the web service request; and transmitting in parallel, from the router, requests to fulfill respective portions of the web services request to each of the at least two remote servers of the plurality of remote servers wherein the transmitting in parallel the requests to fulfill the respective portions of the web services request comprises transmitting in parallel the first send web service request to the first remote server and the second send web service request to the second remote server. ### Claim 8 (depends on 7) The method of claim 7, further comprising: receiving, by the router from the at least two remote servers, a plurality of responses; compiling the plurality of responses into a single response; and transmitting the single response to the at least one client. ### Claim 9 (depends on 7) The method of claim 7, wherein the requests to fulfill the respective portions of the web services request transmitted from the router to each of the at least two remote servers includes UPC information related to at least one product. ### Claim 10 (depends on 9) The method of claim 9, further comprising: receiving, by the router from the at least two remote servers, a plurality of responses, wherein at least one of the plurality of responses comprises at least one of price and availability information related to the at least one product. ### Claim 11 (depends on 9) The method of claim 9, wherein the transmitting the first send web service request comprises first UPC information related to the first product;
