Question

I’m using cocoahttpserver in an iphone app, but when I try to download it (by clicking a link in the standard demo app), my sqlite file (myDatabase.sqlite) arrives on my Mac Desktop as “Unknown” with no suffix at all. However, when I “Save As…” it provides the name fine. I would prefer it to save the file with the sqlite suffix.

So, it must be the suffix causing the problems????

If this is the problem, I cannot seem to find a way in the classes to download the correct file name BUT then change it when presenting it to the browser (with a suffix like .backup, or .db, or something that works).

Anyone know where in the classes to change the download file name so the browser (Safari) will not call it “unknown”? Thanks.

I found someone else’s code (MyAppSales) and in replyToHTTPRequest, I added the Content-Disposition header as below (in one section of the method), and now it works!

if(!isRangeRequest)
        {
            // Status Code 200 - OK
            response = CFHTTPMessageCreateResponse(kCFAllocatorDefault, 200, NULL, kCFHTTPVersion1_1);

            NSString *contentLengthStr = [NSString stringWithFormat:@"%qu", contentLength];
            CFHTTPMessageSetHeaderFieldValue(response, CFSTR("Content-Length"), (CFStringRef)contentLengthStr);

            // ************* added this from MyAppSales
            if ([httpResponse isKindOfClass:[HTTPFileResponse class]])
            {
                NSString *baseName = [(NSString *)[(HTTPFileResponse *)httpResponse filePath] lastPathComponent];

                NSString *contentDispoStr = [NSString stringWithFormat:@"Content-Disposition: attachment; filename=\"%@\"", baseName];
                CFHTTPMessageSetHeaderFieldValue(response, CFSTR("Content-Disposition"), (CFStringRef)contentDispoStr);
            }

        }
