Re: SISCweb & File Upload

Gerardo,

The request object returned by the some of the send-*/* procedures is
the actual HttpServletResponset object. You can most certainly place
more than one call to it.

The response object is also always available through the
(current-response) procedure in the siscweb/response module. [*] So
your file upload module does not technically need to be passed the
response object, and you can keep the (get-bindings) call n place.

Hope this helps,
___
Alessandro
