[Web] Content-Disposition: inline; filename=bla.pdf

For some reason, the adobe pdf reader plugin doesn't care about the filename argument of the Content-Disposition directive when you save the pdf file. The fix is to use friendly URLs, and to build your url with the pdf filename as the last part of the url. For example, consider the following url: view.php?op=pdf&id=100. Before the fix, the plugin would suggest the filename view.pdf, no matter what filename= would be given in the http headers. After the fix, using the url view.php/op/pdf/id/100/myname.pdf, the plugin would suggest myname.pdf, which is exactly what we wanted. Note that friendly urls typically exclude .php extension from the script name, but i didn't bother to make the proper apache config changes to support it. Also note that the script arguments should be separated by /, and no funny characters should appear in between unless properly encoded.
