'Sunucudan alınan yinelenen başlıklar' EPPlus 2.9 ile Chrome 16'daki Hata

Question

EPPlus 2.9 ile oynarım ve Chrome 0'ı kullanarak tek bir .xlsx dosyalarını indirmeye çalıştığımda bazı nedenlerle Duplicate headers received from server hataları alıyorum. IE9).

Ben this tutorial kullanıyorum ve bu kod satırına sorunu dar ettik:

 Response.AppendHeader("Content-Disposition", 
     "attachment; " + 
     "filename=\"ExcelReport.xlsx\"; " + 
     "size=" + fileBytes.Length.ToString() + "; " + 
     "creation-date=" + DateTime.Now.ToString("R") + "; " + 
     "modification-date=" + DateTime.Now.ToString("R") + "; " + 
     "read-date=" + DateTime.Now.ToString("R")); 

Benim kullanıcıaracısı:

Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.75 Safari/535.7 

Ben this Chrome forum page okumaya Krom sevmez virgül (,) Content-Disposition başlıklarında ve bunlar noktalı virgülle (;) değiştirilmelidir.

Herhangi bir fikri olan veya aynı hataları alan var mı?

Answer 1

Ben DateTime.Now.ToString("R") Bunu yaparak sabit Thu, 26 Jan 2012 02:05:44 GMT

üretir, aptalım:

String timestamp_without_commas = DateTime.Now.ToString("R").Replace(",",""); 

Response.AppendHeader("Content-Disposition", 
    "attachment; " + 
    "filename=\"ExcelReport.xlsx\"; " + 
    "size=" + fileBytes.Length.ToString() + "; " + 
    "creation-date=" + timestamp_without_commas + "; " + 
    "modification-date=" + timestamp_without_commas + "; " + 
    "read-date=" + timestamp_without_commas); 

IE huysuz olmak ve Chrome güzel oynamaya alışkınım ...

Aynı sorunu yaşadım ve ek olarak doğru eklendikten sonra da yarı kolon vardı. Sorunumun dosya adında virgül olduğunu gördüm. Bu yüzden onları tire ile değiştirdim.
