How can I add the size of the file to my headers so that people downloading my .rtf files will know how large the files are?

the following code is what I have so far:

setHeader("Content-disposition", "attachment;filename=" + reportType + ".rtf");

is adding  ";filesize=" + filename.size() even close to an answer?

I think it's Content-Length, I think that before you write anything to the stream,set it with the correct Length you are going to write.

Note that thsi is the way of specifying persistemt connections (also called as Keep Alive)

is there a method called getSize() that would return an int of my file in bytes?

for example,

File f = new File("myFile");
int size = f.getSize();

and then in my header I can specify my file size by entering:

content-length: size }
