asp.net - Using Server.TransferRequest to force download of file to browser -

-

i intend use asp.net server.transferrequest send file browser without browser knowing actual path of file being downloaded. example, address download.aspx?id=123 should result in browsers save dialog popping up.

when use server.transferrequest "redirect" to, say, pdf file, contents of pdf file sent browser; however, content shown in browser window - not surprisingly - unintelligible text.

i think there should headers attached response force browser download file, "content-disposition" header doesn't trick.

any ideas on how this?

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
