This issue I experienced was that pdf files would not open in
windows. It turned out that the pdf downloaded to windows was one
byte longer than the pdf uploaded from MacOS9. When I did a side-by-
side comparison (pdfs are readable in a text editor even though there
are non-printing characters) there was an extra line terminator (I
forget which one).

No, I did HOURS of testing on this. A PDF or a JPEG is binary as I
know you know. ;-) But witango looks at any var as TEXT with the
<@length tag. Just like in other languages, you can specify LEN and
LENB for byte length of TEXT or byte length of a binary field,
because it is not always the same. Most of the time it is, but it
occasionally is not.
I have found the best way is to store the data in a db, like mysql,
and then call it out, and use the mysql LenB function to get the
actual binary length.

I think the problem is dependent on the means used to upload the
pdf -- an extra line terminator seemed to get included with
uploads from MacOS9.
I pass my pdfs through an upload filter to remove extra <@CR> and
<@LF> characters at the end of the file.

Be mindful, that using <@length on the pdf data to get the
content-length works 99% of the time, but will be a byte or so
off 1% of the time or so, and will cause the client to not work
right. This is a issue with witango. Search the archives, you may
need to use an external method to accurately calc bytes, or use a
db to do so, etc.

Hi Robert,
Thank you very much for this. You're a great help.

All you have to do, is create a taf that reads in the DATA of
the pdf file, create your own custom header and serve the data
out. The custom header MUST have a correct content-length, or
it won't be compatible with all browsers. content-type should
be application/pdf, and THIS IS THE IMPORTANT PART, content-
disposition needs to be:
attachment; filename=thefilename.pdf
Substitute "thefilename.pdf" with the filename you wish. You
can also even do this with JPEGs or other image formats, and
the browser will not display, but instead download. I use this
technique in witango and php on several sights in production.

Hi Everyone,
I need to create a link to a PDF file that immediately brings
up a download dialog
instead of opening the file. Does anyone know how to do this?
Thanks,
Stefan
