21957 2008-10-29 14:27:51 -0700 WebKit doesn't know how to recover from kCFErrorDomainCFNetwork: 302 very well 2008-10-29 18:01:35 -0700 1 1 1 Unclassified WebKit WebCore Misc. 528+ (Nightly build) All OS X 10.5 RESOLVED INVALID P2 Normal --- 0 matt webkit-unassigned oldest_to_newest 97039 0 matt 2008-10-29 14:27:51 -0700 If I visit a site that breaks the connection such that it generates a error "kCFErrorDomainCFNetwork: 302", it takes a while, sometimes never, for that site to start rendering again. A while could be days. The site itself could be working fine, as I can open the same site in Firefox and curl just fine. The only workaround I have found is to: 1. Empty Cache 2. Delete the site.webhistory file from ~/Library/Caches/Metadata/Safari/History 3. Remove the site's Cookies in Preferences 4. Restart Safari It may be that the last step (removing the cookies) is the deciding factor of the workaround. I have seen this in Safari 3.1.2, GWT Hosted Mode (uses WebKit + SWT) and the latest nightly build as of this bug filing. Searching the web finds many, many people encountering persistent kCFErrorDomainCFNetwork errors like this, so it appears to be a widespread problem. I can generate it pretty easily if I debug GWT in Hosted mode, hit a breakpoint, then open the page I am debugging in a safari browser instance. Interestingly, if I stand up Tomcat and replicate the path that GWT uses (http://localhost:8888/my.module.name/index.html) with a plain HTML file, Safari still shows the 302 error. 97058 1 mrowe 2008-10-29 15:39:57 -0700 For what it's worth, error 302 in kCFErrorDomainCFNetwork is kCFErrorHTTPConnectionLost. 97071 2 matt 2008-10-29 16:23:57 -0700 I have narrowed the workaround down to just deleting the cookies for the website (in my case localhost/...) and restarting all instances of WebKit. I know, doesn't make sense, but it's what I am finding. I'm not sure what it is about the cookies I am saving. I will keep trying to narrow this down. 97083 3 matt 2008-10-29 18:01:35 -0700 The bug is in Tomcat, not WebKit. This WebKit issue can be closed. FYI, I filed a bug with Tomcat: https://issues.apache.org/bugzilla/show_bug.cgi?id=46125
