I have often experienced while developing my web applications that pressing F5 or refresh doesn't produce or refresh the proper result. But when we hit Ctrl + F5 it generates the correct result. What is the basic difference between simple F5 and Ctrl + F5?
I have often also experienced that pressing simple F5 and pressing the Refresh button in the browser also generate different results.
What is the basic difference among all these requests?
CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.
I did small research regarding this topic and found different behavior for the browsers:
See my blog post "Behind refresh button" for more details.
F5 and the refresh button will look at your browser cache before asking the server for content.
Ctrl + F5 forces a load from the server.
You can set content expiration headers and/or meta tags to ensure the browser doesn't cache anything (perhaps something you can do only for the development environment).
F5 triggers a standard reload.
Ctrl + F5 triggers a forced reload. This causes the browser to re-download the page from the web server, ensuring that it always has the latest copy.
Unlike with F5, a forced reload does not display a cached copy of the page.
F5 is a standard page reload.
and
Ctrl + F5 refreshes the page by clearing the cached content of the page.
Having the cursor in the address field and pressing Enter will also do the same as Ctrl + F5.
F5 reloads the page from server, but it uses the browser's cache for page elements like scripts, image, CSS stylesheets, etc, etc. But Ctrl + F5, reloads the page from the server and also reloads its contents from server and doesn't use local cache at all.
So by pressing F5 on, say, the Yahoo homepage, it just reloads the main HTML frame and then loads all other elements like images from its cache. If a new element was added or changed then it gets it from the server. But Ctrl + F5 reloads everything from the server.

I have my two name logos coming in from the right using marquee and stopping exactly where I want (within the and ). When pressing Ctrl + F5 it works perfectly. When pressing F5 only, the images scroll off the to the left. I know Ctrl + F5 clears the local cache, and F5 does not. How can I clear the cache every time the page is loaded or reloaded? Go to https://beiswenger.com/beiswengerassociates and try it for yourself. I need to resolve what should be a simple problem quickly.
I have tried:
With no luck. I have even tried sending the page to a default asp and then back. JBeiswenger
Is there a way to exit the insert mode in Google Colab? Usual Esc doesn't work.
Even jumping out of the code block and jumping back in still activates in Insert mode.
Do you have any browser extensions which might be overriding the default behaviour of your keys? I had the same issue as you, with esc and v both failing to act as expected; but since disabling the Vimium extension, I've had no trouble with exiting Insert mode.
UPDATE: You can disable Vimium for specific sites. Just set an exclude URL filter for https://colab.research.google.com/* in the preferences for Vimium. The exact steps for modifying an extension's settings depend on your browser so I suggest Googling it.
with ctrl + c, I could exit the insert mode.
I am using JDeveloper 11.1.2.3.0
I am having a big problem here. I create a simple page and insert a form, a createInsert button and a commit button for example. I run this page and everything is fine. I create a new record, fill the form fields and then commit. In this moment if I press F5 to reload the page, the browser asks me for confirmation "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I don't understand why it has to repeat any action, I checked for dirty transactions after the commit operation and transactions are clean. If I move from this page to another and back to first it works fine, F5 refreshes without problem.
If I have a table with multiple rows and I update first row for example, and then click the third row and then perform a refresh (Confirm on above message), the third row will obtain the obtain all the information of the first row...
Does anyone know how to deal with this problem?
Ok I found the real problem and solution to this. As I said reopening the page does not bring any problem, but only hitting F5 does. My 'submit' and 'commit' buttons had 'partialSubmit=false' which should perform a total page submit in this case. Apparently this is not "detected" by the browser when pressing F5 although submission is performed. Changing 'partialSubmit=true' to the buttons did the trick. Tung
I'm trying to debug my Chrome extension using
console.log("message");
My extension works fine (for the most part), I'm clicking buttons that call function which perform something. Every function as a consloe.log() debug line.
If I open the chrome console (ctrl + shift + i) after chrome loads, it remains empty, no matter what I do. Chrome is set to developer mode.
Make sure that you are opening the correct dev console. You need to go to the generated background page for the background page console and right click -> inspect popup for the popup console. There was an answer to a similar question with a nice gif, I will link it if I can find it.
I'm an ASP.NET developer, and I usually find myself leaving the webpage that I'm working on open in my browser (Chrome is my browser of choice, but this question is relevant for any browser). My workflow typically goes like this: I write code, I rebuild my project in Visual Studio, and then I flip back to my browser with Alt-Tab and hit F5 to refresh the page.
This is fine and dandy if a form hasn't been submitted since the page was opened. But if I've been clicking around on ASP.NET form controls, the page has posted form data a number of times, so hitting F5 causes the browser to (sensibly) pop up a confirmation message, e.g., "Confirm Form Resubmission: The page that you're looking for used information that you entered...".
Sometimes I do want to resubmit the form, but more often than not, I just want to start over with the page (rather than resubmit form data). The way I usually get around this is to simply add some query string data to the URL so that the browser sees it as a fresh page request, e.g.:
page.aspx
becomes
page.aspx?
(or vice-versa).
My question is: Is there a better way to quickly request a fresh version of a webpage (and not submit form data) in any of the major browsers? It seems like a no-brainer to me for web development, but maybe I'm missing something. What I'd love to see is something like the last item in this list:
F5: refresh page
Ctrl-F5: refresh page (and force cache refresh)
Alt-F5: request fresh copy of the page without resubmitting the form
Go to the address bar and press Enter to submit a fresh GET request. Quick keyboard shortcut is Alt+D, Enter.
Yes, just focus on address bar and press enter.
In Chrome, you can use Ctrl-L to focus on the address bar as well as the suggestions made above.
