Subject: Re: [wsrp] Re: Q about resource usage with http post
We have potentially a lot of information to send; more than the maximum size of a URL (which is also browser dependent). We could chunk the information, send multiple GET requests and re-assemble the fragments on the server, but I'd rather perform a simple POST. There are also security issues. POSTed information is automatically secure when using SSL, for GET encoded data we'd have to do our own encryption (for example if access logging is enabled on the server where the resource is served from). -- Lars "Rich Thompson" <firstname.lastname@example.org To: email@example.com m> cc: (bcc: Lars Hofhansl/PeopleSoft) Subject: Re: [wsrp] Re: Q about resource usage with http post 09/23/2004 12:20 PM As I read your first paragraph, I also went to using the concept of resources as the right way to accomplish what you need (i.e. the updated fragment is a resource from the Consumer's point of view). Is there a particular reason the information you want to transfer has to be via http post rather than get? This sounds a lot like some of the things I did in a previous research project, but we used http get for all the transfers.

I.e. we have to completely bypass the Portlet Interaction model. There seems to be no specific provision for this in the WSRP Spec (V1). For example performBlockingAction() either has to return the complete markup or it has to be followed by getMarkup(), we can't just return some change information and partially update a portlet. (I realize that when multiple portlets are displayed by a Consumer and one of the portlets needs to be re-rendered that the Consumer may re-render all portlet, which breaks our selective refresh paradigm for that case.) For these reasons we're trying to POST to resourceURL in order to handle our data exchange, then update the representation using DHTML based on the exchanged information without triggering any (Consumer visible) refreshes in the Consumer. Now, the V1 WSRP spec in 10.2.1.1.3.1 says that the cosumer is "encouraged to use the same communication style (e.g. HTTP Get or POST)" that was used by the user-agent. That does not seem to mandate that behavior and thus we cannot assume that all Consumers will indeed behave that way. Thanks. -- Lars Rich Thompson wrote: I don't know of cases where people have used http post in this manner, but the spec anticipates that such cases may exist and allows the markup to specify use of post with the requirement that the Consumer then also use post when passing the request on to the resource url. This keeps the Consumer truly acting as a proxy for these resources. Rich firstname.lastname@example.org 09/21/2004 05:36 PM To email@example.com cc Subject [wsrp] Q about resource usage with http post Is HTTP post supported for resource operations according to the spec? My reading of it points to an ambiguous statement to that effect on pg 62, section 10.2.1.1.3.1 Thanks To unsubscribe from this mailing list (and be removed from the roster of the OASIS TC), go to http://www.oasis-open.org/apps/org/workgroup/wsrp/members/leave_workgroup.php .
