＆QUOT;使用无效响应滤波器QUOT的;当从IHttpHandler的COM pressing响应 [英] "Invalid use of response filter" when compressing response from an IHttpHandler

问题描述

我有一个IHttpHandler的返回一个文件。当响应流为com pressed，既可以自动使用Telerik的RADCOM pression或通过明确设置过滤器

I have an IHttpHandler returning a file. When the response stream is compressed, either automatically using Telerik RadCompression or by explicitly setting a filter using

context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);

返回到浏览器的响应是正确的，但在反应的末尾是一些HTML。该HTML包含异常：

the response returned to the browser is correct but at the end of the response is some HTML. The HTML contains the exception:

[HttpException (0x80004005): Invalid use of response filter]
   System.Web.HttpResponseStreamFilterSink.VerifyState() +3928894
   System.Web.HttpResponseStreamFilterSink.Write(Byte[] buffer, Int32 offset, Int32 count) +28
   System.IO.Compression.DeflateStream.Dispose(Boolean disposing) +363
   System.IO.Stream.Close() +28
   System.IO.Compression.GZipStream.Dispose(Boolean disposing) +63
   System.IO.Stream.Close() +28
   System.IO.Compression.DeflateStream.Dispose(Boolean disposing) +595
   System.IO.Stream.Close() +28
   System.IO.Compression.GZipStream.Dispose(Boolean disposing) +63
   System.IO.Stream.Close() +28
   System.Web.HttpWriter.FilterIntegrated(Boolean finalFiltering, IIS7WorkerRequest wr) +754
   System.Web.HttpResponse.FilterOutput() +121
   System.Web.CallFilterExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +174

如果我要确保响应不COM pressed，响应包含也不例外。

If I make sure the response is NOT compressed, the response contains no exception.

什么与了？

推荐答案

这似乎与此有关：<一href=\"http://stackoverflow.com/questions/3653250/gzipstream-is-cutting-off-last-part-of-xml\">GZipStream被切断XML 的最后一部分

It seems to be related to this: GZipStream is cutting off last part of XML

我删除了COM pression模块，它似乎是所有好现在。

I removed the compression module and it seem to be all good now.
