<div dir="ltr">>If you have an userserver url in some db in the inventory server, then this needs updating when a user changes grids<br><br>this depends on what exactly "change grid" means:<br><br>1. if it means user registers at GridService1 and want to login to a regionserver at GridService2, THEN<br>
That is my point, and I think that is the point maybe I did described clearly:<br>just for "grid jump", *** user need not to change its grids(here means userserver_url)***<br>user can only register in one gridservice(userserver), and he can keep its account there forever, and the user still can travel to other gridservices.<br>
[avatar portability mechanism:]<br>because when the an user login to a "foreign region" in other gridservice<br>* the user tells the "foreign region" to claim its identity from its original userserver.<br>
* the user tells the "foreign region" to bring its belongings into the world(appearance, inventory).<br>In this case "userserver_dictionary" *need not to be updated*<br><br>2. if it means: user register another account at another
gridservice. like today I have been using hotmail, and now I am using
gmail. THEN<br>
* if the user cares about his/her belongings, by using the portability mechanism I methioned in 1, the user can still use his/her previous<br> inventory/asset service, because inventory/asset server are independent., in this case, yes, "userserver_dictionary" *need to be updated*,<br>
(to set userserver_url point to current userservice) but this kind of "change" won't be frequent, like today, how many free mail accounts<br> are you "really" using, or how many times you changes your mail account ?<br>
<div class="gmail_quote">* if the user want to start a new life, maybe he/she does not mind
start from "zero", like today I switch to gmail, I can not read my past<br>
mails in hotmail in gmail. why I change to gmail? because my hotmail is full with spam, I donot want to clean it.<br><br>regards,<br>lulurun<br><br>2008/7/25 Michael Wright <<a href="mailto:michaelwri22@yahoo.co.uk">michaelwri22@yahoo.co.uk</a>>:<br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Well no, as each user should have a inventory server url in their userprofile db. So that is looked up and the login server then asks for permission on the inventory server to access a users inventory and to push the session id. So yes you need to set up permissions on the inventory server to allow the various "grids" to access a users inventory. <br>
<br>But as there could be multiple grids authorised for a user, it allows the user to login and out of those grids while keeping the same inventory. If you have a userserver url in some db in the inventory server, then this needs updating when a user changes grids (or if multiple urls were saved, then the active one needs setting). And it certainly shouldn't have to be done manually so again it requires a push. <br>

<div dir="ltr">Comparing "pull" and
"push", I would like to say:<br>pull is "require setting a lot of urls on different servers anyway", but push is full with vulnerability.<br><br></div></blockquote><br></div><p>
