WebContents.loadUrl() without cache

[maxkueng]

Currently there is no option to load content in to a BrowserWindow without loading from the cache. I don't want to disable caching entirely through the --disable-http-cache switch as I want to use caching during app use. But I want fresh content to load when starting the app.

My current workaround is to load the content using loadUrl() and then use reloadIgnoringCache() to load the un-cached content as soon as it has finished loading. But it feels hacky and the window flickers.

Is there a way to not read from the cache initially but still enable caching? Or could it be added by adding a second argument to loadUrl() like loadUrl('http://github.com', ignoreCache), or maybe add a function like loadIgnoringCache(url)?

Chromium didn't expose an API to ignore cache when loading URL, so it is not easy to achieve that.

Thanks for looking in to it! Can we leave this open in case Chromuim ever implements such an API?

webContents.loadURL(url, {"extraHeaders" : "pragma: no-cache\n"}) should work.

@deepak1556 awesome find! I think we should add it to the docs

[deepak1556]

@etiktin have added it to the docs here #3432

Closing since this was fixed by #3432

I added @wv.loadURL(@wv.src, {"extraHeaders" : "pragma: no-cache\n"}) but it is not updating js files included in html , any idea?

[wasimxe]

I tried every combination of extraHeader, cache-control:no-cache,no-store etc and expires set to 0 or past time, nothing is working.

Recently I had some issues too.

Cached iframe is making it very difficult to develop. Wish I could load fresh.
