从服务器收到的重复标题 [英] Duplicate headers received from server

问题描述

从服务器收到的重复标题

Duplicate headers received from server

服务器的响应包含重复标题。此问题通常是网站或代理配置错误的结果。只有网站或代理管理员才能解决此问题。

The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue.

错误349（net :: ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION）：收到多个不同的Content-Disposition标头。这是不允许的，以防止HTTP响应分裂攻击。

Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.

我发现这个错误，当输出到pdf的铬。 b
$ b

I found this error while exporting to pdf in chrome.

Response.Buffer = false;
Response.ClearHeaders();
string ext = objProp.PACKAGEFILENAME.Substring(objProp.PACKAGEFILENAME.LastIndexOf("."));
string ext1 = ext.Substring(1);
Response.ContentType = ext1;
Response.AddHeader("Content-Disposition", "target;_blank,attachment; filename=" + objProp.PACKAGEFILENAME);
const int ChunkSize = 1024;
byte[] binary = objProp.PACKAGEDOCUMENT;
System.IO.MemoryStream ms = new System.IO.MemoryStream(binary);
int SizeToWrite = ChunkSize;

for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + ChunkSize)
{
    if (!Response.IsClientConnected) return;
    if (i + ChunkSize >= binary.Length) SizeToWrite = binary.Length - i;
    byte[] chunk = new byte[SizeToWrite];
    ms.Read(chunk, 0, SizeToWrite);
    Response.BinaryWrite(chunk);
    Response.Flush();
}
Response.Close();

推荐答案

这个有点老，但在谷歌排名高，所以我想我会抛出我从 Chrome，pdf显示，从服务器接收到的重复标题

This ones a little old but was high in the google ranking so I thought I would throw in the answer I found from Chrome, pdf display, Duplicate headers received from the server

基本上我的问题是，文件名包含逗号。做一个替换逗号删除它们，你应该没问题。
$ b

Basically my problem also was that the filename contained commas. Do a replace on commas to remove them and you should be fine. My function to make a valid filename is below.

    public static string MakeValidFileName(string name)
    {
        string invalidChars = Regex.Escape(new string(System.IO.Path.GetInvalidFileNameChars()));
        string invalidReStr = string.Format(@"[{0}]+", invalidChars);
        string replace = Regex.Replace(name, invalidReStr, "_").Replace(";", "").Replace(",", "");
        return replace;
    }
