content: Definitely seems faster, even though CloudFlare can only cache static assets. I wonder if they do some additional opportunistic loading of content so when the browser requests images/scripts etc., the edge node has already got them in memory from the main server.Nice one Dave.

content: It may be a coincidence but since the change whenever i'm on eevblog here, firefox is sluggish and eats cpu cycles. Literally as I type this, from time to type it stops printing characters on screen for a couple of seconds becuase I guess Firefox is poorly threaded and eats 100% of a cpu core.Looking at what runs in that thread, it seems the stuff that eats cpu is the javascript engine of Firefox. I'll keep investigating..later edit: found the culprit after closing each tab in the browser, it was another website's scripts.

content: Quote from: BravoV on April 06, 2014, 09:34:31 amThis is the why I dislike Cloudflare - I've seen the same on many sites using Cloudflare and in some cases it totally breaks the functionality of the site (forms not submitting correctly, login cookies going astray, etc.).

content: Mariush, thanks, I will take a look on that.Mean while, I've experienced > 5 same errors today.I don't have the expertise on this global web cache infrastructure, just thinking is it possible that I'm the only the genius on earth ... <sarcasm mode :ON> ... that have invented the idea of this ultra advance algorithm ?Looks like the current main loop algorithm there is like this :IF <requested web page is available at the cache> AND <and cache is not expired (under certain criteria)>THEN <reply the request from the cache> ... (life as usual)ELSE <pop out the error screen, and ask the user to go directly to the live/real server>My new invention :IF <requested web page is available at the cache> AND <and cache is not expired (under certain criteria)>THEN <reply the request from the cache> ... (life as usual)ELSE <forward the request "AUTOMATICALLY" to the real/live server and let it handles the request it self directly>Just wondering I managed to patent this ultra cool elite algorithm, I must be filthy rich right ?<sarcasm:OFF>Dave, don't mean to bash this feature, actually I really appreciate your efforts and intentions to improve your user's experiences at your web site, but so far what my experiences is this thing is making it worse.Before this, I only had smooth and responsive web experiences from eevblog, or totally offlined/dead because of the server problems, which is normal and totally expected.Is this thing is still in "trial" period or you already signed the contract with them ?

content: Quote from: BravoV on April 06, 2014, 03:48:16 pmIsn't that exactly what it's doing, per the information on the error page? It was Dave's server that had its fingers stuck in its ears when CloudFlare forwarded the request, so it put the error page up as a result of not being able to retrieve the page you requested from the backend...

content: Quote from: baljemmett on April 07, 2014, 12:18:41 amYes, this is exactly how CloudFlare works, give or take some details. The problem here is that CloudFlare was apparently unable to contact the backend (Dave's server).My guess would be that Dave's server has had some per-host connection limits or other "security" features enabled, and that now many requests are coming from the CloudFlare frontends rather than diverse user addresses and tripping those limits, causing intermittent failure. Worse, this will probably be isolated to users in certain "busier" regions or the like, so for many users will probably never happen.Also Firefox anyway saves input form data in the history, so if a submit fails you can usually just go back and the boxes will still be filled in. Seems to work on this forum. Some JavaScripts break it, but it usually works without any addons.

content: Quote from: ve7xen on April 08, 2014, 04:17:04 amBut bots have for some time now used ecmascript (javascript) libraries to extract things attempting to hide behind javascript. I haven't kept track of how much javascript the bots run. It's configurable I'm sure. Bots and screenscraping are a high art (low art?).Using SSL (i.e. https) may be a better solution.

content: Quote from: BurtyB on April 08, 2014, 04:31:49 pmI did say bots use js. SSL is just good sense these days. At the very least for authenticating. It seems this forum is all plain text authentication. Pretty old-school. And makes it vulnerable to lots of devious stuff.I don't know if bots would go to the trouble of making SSL connections or not. You're asserting they do.Cheap is always a relative term. Multiply cheap times millions or billions and then what might have been considered cheap isn't. CPU hardware might be cheap but running it at max/overclock isn't so cheap when the electron bill comes.

content: No, at best he will get credit for the hours the server was down.Seriously Dave, this Hostgator is so unreliable if I were you I would ditch them.I have dedicated servers rented at another company and other than the rare DDOS on the network every few months (happens everywhere), the servers are rock solid. And that email spam thing i noticed on twitter... not sure what's that about but I never had problems with this company I work with.They recently added configurations with the latest quad core with hyperthreading from intel, 8GB and more, from about 135$ a month, gigabit ports with 10TB included... the only downside for you is they're self-managed, costs about 80$ extra to manage them for you .. but you have kvm over ip included, and you have people to help you out and configure it.Check them out if you want :http://www.swiftway.net/offer/unmanaged-single-processors/
