Normaly this should not be to big a problem but, IIS sets no cache on ASP pages with an error. This makes it much harder to debug since sometimes the next fetch does not reproduce the error. Reproducible: Always Steps to Reproduce: 1.Try the url 2.Reload the url 3.View source 4.Works fine 5.Enter something in the textfield and submit 6.View source Actual Results: It tries to repost the form Expected Results: It should Not repost the form since that could change the state of the server. I do not know if this problem existed before but I have not seen it before 1.4 final and since I do all my development on work in mozilla I think I should have seen it before, but I am not 100% certain. This will probably only affect developes and I think I can do a workaround for my pages but still, it annoying to have to rewrite a page to debug it. I do not whant to switch to IE because I still have to reverify everything in mozilla.

Over to darin; the problem here is that the page in question is a 500 error page, and we don't cache error pages. Per discussion, we should probably cache these and expire them immediately, so that back/forward/viewsource work but reload refetches the right thing. David, could you please keep the test page up for a bit so we can test possible fixes?

bz says that fixing this should fix a similar problem with HTTP auth pages. STEPS TO REPRODUCE 1. Load http://www.sbscpressinfo.org/ 2. Cancel the prompt. 3. View source ACTUAL RESULTS You are prompted again. EXPECTED RESULTS The source with no prompt.

no time to work on this now... the solution, i think, is to cache error pages with zero freshness lifetime. as a result, they will be accessible from the cache when loading the page via back/forward, viewsource, or saveas. however, normal browsing will always hit the server.

Comment on attachment 153068 [details] [diff] [review] Like so? actually, i think we want to use an expiration time of 0, which implies that the document is already expired (0 means the Epoch, 1970). see nsHttpChannel::UpdateExpirationTime() where we set 0 as the expirationTime in cases where 'Cache-control: no-cache' is returned from the server, for example. i'm also a bit concerned about logic in ProcessNormal that calls InitCacheEntry. it calls UpdateExpirationTime. perhaps the solution here is to coerce nsHttpResponseHead into returning PR_TRUE for MustValidate(). that may be better. in fact, you could probably just use the response code for that.

Er, make that !=2 && !=3 in the patch, I think. We do want to allow caching of redirects.
Comment 14•20 years ago
|
||
yeah, something like that. we may want to synchronize this filter with the switch-case in nsHttpChannel::ProcessResponse() to be 100% sure that it doesn't have unexpected side-effects. like what about the 2xx responses not covered in the switch-case. i'll need to think about this some more, and do some thorough testing. what sort of testing have you done?
Assignee | ||
Comment 15•20 years ago
|
||
Synchronizing makes sense. I can do that. I've tested that it fixes this bug, but I don't have any error pages on hand that would allow themselves to be cached in a detectable way...
Comment 16•20 years ago

Comment on attachment 153080 [details] [diff] [review] So more like this? In fact, this is incorrect since some redirects may be cached. Even a 302 can be cached if the server sends a Cache-control header that specifies a max-age or some equivalent header.

My testpage from when I reported the bug still exists, does it require any changes to test the patch, please just tell me what and I will try to update the testpage or create a new one.

David, your testpage is one of the things I tested the patch on. It doesn't need any changes that I can see. Darin, the compiler does optimize all that away. Fix checked in.
