When one assigns to window.location, the web browser automatically invokes attachment-handling according to the contentType if the response's Content-Disposition is set to "attachment". The same thing happens if the request is elicited by a traditional form submittal or triggering an href linked to the Content-Disposition==attachment target.
My use case seem pretty simple to me. I need to post a bunch of data via postBody, and the response will be an attachment. Both parts are prosaic and simple, but web searches find nothing on the Internet of anybody trying to do both of these things. Seems that as soon as Ajax is introduced, you lose the ability for the browser to automatically handle attachments, and I find no ability to handle them manually via w3c DOM API or PrototypeJS API (viz. to have the browser open the Open/Save-As pop-up). To maybe prevent a couple exchanges... I do need to use "post" method due to the nature of the data (that the attachment will be generated from). I do not want to hold/cache data on the server for a subsequent traditional fetch: This is clean and atomic as a single post transaction and I don't want to introduce memory contention issues and the opportunity for memory leaks. I tried PrototypeJS's form.request() in hopes that if no callback was specified maybe the browser's default handler would be used... but it ain't. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
