Aren't you supposed to use Shift-F5 (at least in chrome) for a hard refresh - not Ctrl - F5.  https://support.google.com/chrome/answer/157179?visit_id=1-636338263045956762-2405452703&hl=en&rd=2 {{unsigned ip|108.162.219.136}}
:I believe that's correct. It is likely browser dependent. --[[User:Arccos|Arccos]] ([[User talk:Arccos|talk]]) 15:27, 23 June 2017 (UTC)

:Erratum: The middle hard-refresh option is missing something - it lists only modifier keys. [[Special:Contributions/172.68.142.185|172.68.142.185]] 15:32, 23 June 2017 (UTC)

:It appears that the "hard refresh" option is a real option, but that the keyboard shortcuts in the comic may not be correct. The above user's linked material suggests that the keyboard shortcut for a hard refresh, labeled "Reload the current page, ignoring cached content", is, in Chrome, SHIFT-F5 or CTRL-Shift-R on Windows and APPLE-Shift-R on a keyboard for MacOS. This is in contrast to the comic, which currently lists CTRL-F5, CTRL-Up, and APPLE-UP-R as the shortcuts. [[Special:Contributions/162.158.74.105|162.158.74.105]] 15:33, 23 June 2017 (UTC)

::That's not an "UP," the symbol ⇧ represents the SHIFT key. Indeed it appears Randall omitted the 'R' inadvertently. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 15:46, 23 June 2017 (UTC)

:Randall says the keys are examples, meaning some may missing. But for me it looks like the most common shortcuts. Except the hard refresh by pressing CTRL+SHIFT, that's nonsense because a F5 or R should follow. I'm sure we will see a picture update soon. Stay tuned...--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 15:44, 23 June 2017 (UTC)

:Ctrl-F5 works across every browser. It does appear that Shift-F5 also works in Chrome. [[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 23:35, 23 June 2017 (UTC) 

The missile launch keys can be totally identical for the two-man rule to work; the thing is not that they are interchangeable, but that the locks are too far apart for one person to operate both. [[User:Chrullrich|Chrullrich]] ([[User talk:Chrullrich|talk]]) 18:49, 23 June 2017 (UTC)

* Big Bang refresh - restarts universe just to be sure there's nothing stuck in cache.  (Of course in EMACS, that's just good old: C-x M-c M-bigbang).  :-)  [[Special:Contributions/162.158.69.39|162.158.69.39]] 20:41, 23 June 2017 (UTC)



It looks like the "harder refresh" shortcut also requires two keyboards to work, since the "hyper" key seems to only exist on the space-cadet keyboard, which does not have an F5 key. [[Special:Contributions/162.158.74.105|162.158.74.105]] 19:12, 23 June 2017 (UTC)

Gmail does not update instantaneously at all. I don't know how many times I've gotten a notification from my RSS feed, and then have to go to Gmail and press refresh. And that's not even counting external email. I frequently use the Gmail refresh button. [[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 23:30, 23 June 2017 (UTC)
:That's weird, it definitely does for me. Sometimes it'll even update with the new unread emails before I get a notification that I got a new email. It updates faster than my work email. [[User:OldCorps|OldCorps]] ([[User talk:OldCorps|talk]]) 10:35, 24 June 2017 (UTC)

I also find it funny that this page uses an additional type of refresh: the "purge server cache" kind.  [[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 23:30, 23 June 2017 (UTC)

Powercycling datacenter can't be that long downtime unless the servers starts checking discs. And sometimes remotely triggering soft reset of server would really help user of incorrectly written application - servers are generally configured in way which allows them to start all needed services automatically. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:47, 23 June 2017 (UTC)

Dear [[User:Dgbrt|Dgbrt]], before deleting things and writing on topic you don't know about, please at least read [https://tools.ietf.org/html/rfc7234#page-22 this], [https://superuser.com/questions/17464/difference-between-ctrlrefresh-and-ctrlshiftrefresh this] and {{w|Elasticity_(cloud_computing)#Example|this}}.{{unsigned ip|162.158.90.12}}
:Hi IP, please sign your posts with <nowiki>~~~~</nowiki>.
:*I have mentioned RFC 7234 meta-tags for suppressing caching.
:*"Difference between Ctrl+Refresh and Ctrl+Shift+Refresh". This an old QA from 2009 and still browser dependent. The HTTP-Response "304 Not Modified" isn't always reliable as I also have mentioned.
:*Your reboot statement doesn't belong to any cache issues. I will move it to the ''harder refresh'' section.
:Please stop the edit war by just undoing content. I have rewritten something by using many existing phrases. Please read my edits first before becoming upset.

::No war. I am clearly bad at explaining, so I'll not touch this explanation any more; you are free to fix it the way you want. But at least investigate the issue first, since your proposed sentence showed that you are not familiar with the issue. {{unsigned ip|162.158.90.12}}

;Off-topic transcript discussion
I want to say that ELinks (the text-based web browser that I, for some reason, have on my Ubuntu) displays [//jacobds.tk/ExplainXKCDonElinks.png this] for the talk section. Isn't the transcript for text-based web browsers on comics where the official transcript fails? Also, I can't figure out how to put headers in.

:I don't understand your problem. Are you talking about the talk section or the transcript? And what's wrong except the inverse text?--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 10:44, 24 June 2017 (UTC)
:The discussion area is enclosed in a div tag with some sort of background and text color settings. Your copy of ELinks is probably trying to emulate the background for you. --[[Special:Contributions/162.158.62.9|162.158.62.9]] 02:25, 25 June 2017 (UTC)

It would be nice if the transcript section here would use words to describe what the symbols are. Or possibly a separate table in the explanation section. Thanks [[Special:Contributions/108.162.219.112|108.162.219.112]] 23:49, 24 June 2017 (UTC)
:That's the reason why it's still incomplete. A real transcript doesn't need a table but a description what's in the image. This includes the full text but also a description of the content like pictures or symbols.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 11:28, 25 June 2017 (UTC)

Looks like Randall missed out a couple of intermediate refreshes:
* Service refresh: restarts the HTTPD service on the web server, clearing out the services's cache
* Warm server reboot: restarts the OS on the web server, clearing out the OS's cache
The cold server reboot usually clears out hardware caches, but the cache of battery-backed RAID controllers will survive a cold reboot.

-I think part of the joke is also that harder/hardest refers to the ''difficulty'' of using those shortcuts, instead of just the implications of the refresh command. --[[Special:Contributions/162.158.222.100|162.158.222.100]] 14:22, 26 June 2017 (UTC)
-"And rebooting an actual physical server upon a web page request is not possible, unless there is a software or operating system bug that will cause exactly this."
-This is not exactly correct. It would be very possible to write functionality into a webpage (deliberately; not a bug) to reboot the server that it is running on or another server. This functionality would need server credentials to do so, provided by either the web coder or the user. This would be useful in e.g. a cloud infrastructure management dashboard. It would be a very bad idea to a public facing webpage without credentials required to prove that the user is authorized to perform reboots of the given servers.{{unsigned ip|108.162.216.190}}
-:Maybe it should read "common web pages" or something similar, because you're right. There are administrative web pages like [http://webmin.com/ Webmin] capable of doing exactly this.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 17:02, 26 June 2017 (UTC)
