ASP.NET OutPutCache VaryByParam 和 VaryByHeader 与 AJAX
我正在尝试使用 VaryByParam 和 VaryByHeader 进行一些缓存。当 AJAX 请求传入时，我返回部分 XHTML。当收到常规请求时，我会发送带有页眉/页脚的部分 XHTML 页面。
我尝试通过执行以下操作来缓存页面：
[OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )]
但是这不起作用...如果我先执行常规请求然后运行 AJAX 调用，我将获得完整的缓存页面而不是部分页面，反之亦然。似乎 VaryByHeader 被忽略了。是因为正常请求时省略了 X-Requested-With 吗？或者也许它正在执行 VaryByParam 或 VaryByHeader？
我明显的解决方法是让 AJAX 请求调用一个仅返回部分页面的不同方法，但是如果可能的话我想避免这种情况。
我将 ASP.NET MVC 1.0 与 OutputCacheAttribute 一起使用。
I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer.
I tried to cache the page by doing:
[OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )]
However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader?
My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible.
I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

根据 此 MSDN 参考，VaryByParam 中的多个值应该用分号分隔，而不是逗号分隔。
According to this MSDN reference, multiple values in VaryByParam should be semicolon separated, not comma separated.
尝试使用 www.fiddlertool.com 检查标头并查看它们是否首先被传递。

您的持续时间设置为 5 秒。这是故意的吗？我怀疑这可能与您的缓存超时有关。
Your Duration is set to 5 seconds. Is this intentional? I suspect might have something to do with your cache timing out after this period.
