Re: HTML field value size limit

Aaron,

Another option is Java. I know that there are several good
servlet implementation available for the downloading. The
way I have handled uploads is to use the file upload tag
that is part of the Struts Tag Library. It is not perfect, but if
you are using Struts, 10 minutes tops and you have an
upload defined. You can get more information about
Struts from http://jakarta.apache.org/struts. O'Reilly also
has an upload class.

To answer Bob's earlier question. The servlet container
in this case should define the upload target directory. That
is part of the Servlet 2.3 specification, I don't think it has
always been part of the spec.

First, you need to define the form as:
<FORM ACTION="/your/cgipgm" method="post"
enctype="multipart/form-data">

When your CGI program runs, you must read from standard
input until there is no more data, which means you most
likely will call it more than once, depending on the size of
the file.

Now, the biggest problem here is that the data is not just
the file name.  You will have the header of the file(s),
describing it/them, it's name, the boundary names, etc.
It's tricky to find these boudaries and seperate the data.
The boundaries are used to seperate multiple files in the
data stream, as well as mark the ending of the data stream.

My 2nd eRPG book has an example of how to do this.  It
allows you to upload 1 to n files using RPG.  It then allows
you to specify where to store the file in the IFS.

It's tricky with RPG.  But not impossible.
