ASP.NET的url MAX_PATH限制 [英] ASP.NET url MAX_PATH limit

问题描述

我已经找到了ASP.NET的一个问题，我至少还知道难倒了另外一个人那里。我们试图使用一个HttpModule来处理通配符
请求到Web应用程序。生成的URL是动态的，可以
可能是几个长一百个字符。不幸的
似乎是在该限制ASPNET_ISAPI.DLL文件的限制
在URL中的MAX_PATH路径的长度，这是很难$ C $音像
260个字符。

I've found an issue with ASP.NET that I know at least has stumped one other person out there. We were trying to use an HttpModule to handle wildcard requests to a web application. The generated url is dynamic and could potentially be several hundred characters long. Unfortunately there appears to be a limitation in the aspnet_isapi.dll file that limits the length of the path in the url to MAX_PATH which is hardcoded at 260 chars.

有没有其他人遇到了这一点，并找到了解决这个限制的一种方式？
查询字符串参数是不是一种选择。

Has anyone else ran into this and found a way around this limit? Query string parameters are not an option.

谢谢，

推荐答案

这是ASPNET_ISAPI.DLL一个已知问题，目前还没有解决方法。在运行您的网站时，您没有看到这个问题的原因内置Visual Studio的Web服务器（又称卡西尼）是因为它的所有管理code和不依赖于ASPNET_ISAPI.DLL。

This is a known issue with aspnet_isapi.dll and there is currently no workaround. The reason you don't see this issue when running your site in the built-in Visual Studio Webserver (aka Cassini) is because it's all managed code and doesn't rely on aspnet_isapi.dll.

这将在ASP.NET的未来版本中得到解决。

This will get addressed in a future version of ASP.NET.
