The "theory" is that you use MIME multipart forms as defined in RFC1867. Your form must be specified using enctype="multpart/form-data" instead of the usual urlencoded. Use the input tag <input type=file name=upld> to give the user a 'file-open' dialog box in the browser to select the file to upload. Each file that the browser then sends to the server in the upload is separated from the others by a unique boundary line that is guarenteed not to appear in the data, usually something like ----------------------1234567
where the digits are a pseudo-random sequence. Following the boundary line are a couple lines telling you what you've got, e.g. -------------------------------1234567 Content-Disposition: form-data; name="myfile"; filename="ad.gif" Content-Type: image/gif <your file content> You can parse the details directly from perl's %ENV hash and STDIN that the server hands you or use CGI.pm which takes care of the parsing and will give you a handle to the file. > A quick question -- > > Can anyone explain the "theory" of file uploads via browser to me?
