Hi Rizwan, there can be more ways of implementing your scenario. Here are two of most popular ones: 1. Using rewritehost("IP_OF_YOUR_PROVIDER") and then call t_relay() to send the request out. 2. Using directly t_relay("IP_OF_YOUR_PROVIDER") without rewriting the RURI host. The difference between the two approaches is that in the case of rewritehost() function u will alter the domain of RURI forcing it to be the ip address of your provider. In the second case, u will no longer alter the domain, but instruct t_relay() not to find the route by itself (no dns lookup or any other way) but send the request as it is to the IP which u specify specify. For more info, please consult the documentation of the two functions: http://openser.org/dokuwiki/doku.php/core-cookbook:1.2.x#rewritehost_sethost http://www.openser.org/docs/modules/1.2.x/tm.html#AEN345 Hope that helps, DanB On 7/4/07, Rizwan Hisham <rizwanhasham(a)gmail.com> wrote:
