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
