Summary0002606: Refresh page fails to refresh
DescriptionClicking the refresh tool fails to refresh the page.
Steps To ReproduceLoad a page in NetSurf, update some text on that page then request that page again. The page is not updated. Quitting and re-running NetSurf still displays the old page. If I run Otter-Browser it displays the updated page so it can't be an external cacheing issue.
Additional InformationDefault cache choices.
TagsNo tags attached.

 I have tried unsuccessfully:
quitting and rerunning NetSurf
restarting the machine
powering down the machine for 30s
deleting cache files

Where is it storing the page?

 The new page has now loaded without a refresh. It's over 1 day since I last loaded the old page.
I've also found a completely separate cache in !Boot.Resources.!Cache.Caches.Default.Netsurf which I assume NetSurf now uses.

OK, so the disc cache expired and the page reloaded. That doesn't change my original issue. Refresh should reload all parts of the page from the server, not from a local cache which is pointless.

 Reload logic is:

frontend -> browser.c:browser_window_reload()
browser.c:browser_window_reload() -> content.c:content_invalidate_reuse_data()
content.c:content_invalidate_reuse_data() -> content.c:content__invalidate_reuse_data()
content.c:content__invalidate_reuse_data() -> llcache.c:llcache_handle_invalidate_cache_data()

llcache.c:llcache_handle_invalidate_cache_data(llcache_handle *handle)
{
    handle->object->cache.no_cache = LLCACHE_VALIDATE_ONCE;
}

browser.c:browser_window_reload() -> browser.c:browser_window_navigate(bw, hlcache_handle_get_url(bw->current_content))
browser.c:browser_window_navigate() -> hlcache.c:hlcache_handle_retrieve()
hlcache.c:hlcache_handle_retrieve() -> llcache.c:llcache_handle_retrieve()
llcache.c:llcache_handle_retrieve() -> llcache.c:llcache_object_retrieve()
llcache.c:llcache_object_retrieve() -> llcache.c:llcache_object_retrieve_from_cache()

enumerate ram cache for match (should match given object cache validity was set above
if not found enumerate disc cache for match

llcache.c:llcache_object_retrieve_from_cache() -> llcache.c:llcache_object_is_fresh()
checks object->cache.no_cache == LLCACHE_VALIDATE_FRESH

if found object is fresh, use it (should not happen from above validity clearing)

if object found but needs freshness check, clone existing cached object and start fetch for it

llcache_object_fetch()

that is what should happen. will setup test to see what does happen

 OK. The original problem cleared once the earlier fetch had expired (after 24 hours). However I have a similar problem with another site (mmpa.org.uk).
I have set disk cache to 0, and added the line above to Choices.
NB I had to open the choices file in the usual way since the above method produced an error on saving (path variable had multile entries etc).
I then ran http://www.mmpa.org.uk/ and it loaded correctly.
