I'm getting a LoadFailed event fired with error code -400 when a user clicks a button on my site that runs javascript:history.back(); I can't find -400 in the error code enumeration. What is this error and why would it fire?

Hi,
400 is CACHE_MISS. You can probably force a refresh in that case.
Thanks!

Does that mean my app is not caching the pages? The same javascript function works fine under the .NET WebBrowser control

Hi,
It depends. The browser engine can decide to throw older page out of the cache. The page may also have a cache policy that prevent it from being cached. Different browser may also have different default policies. CACHE_MISS is the same as the common "this page is outdated, please refresh" message you see with regular browsers.
Thanks!
