It really sounds as though you're just writing a calculation application that accepts the interest /calc1/arg1/arg2, gathers additional content with interests related to /arg1 and /arg2, and on receipt of that content can perform the desired calculation and produce the signed content under the original /calc1/arg1/arg2 name. The app that generated the original /calc1/arg1/arg2 interest should be assigning an appropriate lifetime for that interest, and managing the timeout/retry... if it times out it can re-request it. If the application has completed the calculation it will be able to answer without redoing the calculation (and requesting the content for /arg1 and /arg2 again).</div><div><br class=""></div><div>-- Nick</div><div><br class=""></div><div><br class=""><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div class=""><br class=""></div><div class="">>>Nick</div><div class="">Thanks, and sorry for my lack of explanation.</div><div class="">I dont care about load balancing on the current stage.</div><div class=""><br class=""></div><div class="">>>Lan</div><div class="">I was trying to implement this with forwardInterest method from ASF.</div><div class="">Thanks your advice.

Just want to mention that when the ASF strategy does probing, it make a copy of the received Interest and sends it over a face that it wants to probe. But this interest has the same name as the received interest, so it’s not the same as what the original poster
asked for.<br class="">
