Newbi CGI question

Hi all ~ Carl Sassenrath uses the following construct in his CG tutorial Creating and Processing Web Forms with CGI : switch system/options/cgi/request-method [ "POST" [ data: make string! 1020 buffer: make string! 16380 while [positive? read-io system/ports/input buffer 16380][ append data buffer clear buffer ] ] "GET" [data: system/options/cgi/query-string] ] data Goldman & Blanton simply use 'input to retrieve POSTed data switch system/options/cgi/request-method [ "POST" [data: input ] ] [ "GET" [data: system/options/cgi/query-string] ] data ] I am sure that Carl will have his reason for doing things the way he does - so my question is: Why would he choose the markedly more complex way of doing things in this case? Thanks for shedding some light on this, Kai

I think you'll find that the second method will lose data on large posts. The data lost is dependent upon the OS. On 3/5/06, Kai Peters <kpeters-vu-ware.com> wrote:

Hi Kai, On Sunday, March 5, 2006, 3:16:23 AM, you wrote: KP> switch system/options/cgi/request-method [ KP> "POST" [data: input ] This does not account for binary input data; also, input will give you only one line of text, so it wouldn't work in many cases. It should be noted that it is possible to avoid using READ-IO by setting the input port to binary mode and using COPY/PART with the expected input length (from Content-Length, maybe capped to a reasonable maximum).
