Transferred is the compressed size of all resources. You can think of it as the amount of upload and download data that a mobile user will use in order to load this page. Resources is the uncompressed size of all resources. 

Question: Can you all think of better words to describe these two values? We get this question somewhat often.

In addition to the other answers, if you have filtered the results you will see two numbers in one column, first one indicating the size for the filtered requests and the latter for the total size of requests.

For example if you have filtered the results to only display XHR requests and you see `1 MB / 2 MB transferred` at the bottom, that indicates 2 MB has been transferred in total, of which 1 MB are XHR requests.

When I want to unstage a staged file, all of my Git tutorials show something like:

```
$ git add *
$ git status
On branch master
Changes to be committed:
  (use &quot;git reset HEAD &lt;file&gt;...&quot; to unstage)

    renamed:    README.md -&gt; README
    modified:   CONTRIBUTING.md
```

This hint tells us to use `git reset` for unstaging a staged file.

But instead, in my terminal, I see:

```
git status
On branch master
Changes to be committed:
  (use &quot;git restore --staged &lt;file&gt;...&quot; to unstage)
	renamed:    cat.js -&gt; catcat.js
	renamed:    tolendo.gogo -&gt; tolendo.txt

Untracked files:
  (use &quot;git add &lt;file&gt;...&quot; to include in what will be committed)
	readme (copy).md
	tolendo (copy).txt
	zing (copy).html
```

My terminal tells me to use `git restore --staged` but the tutorials, as well as [Git’s website](https://git-scm.com/book/en/v2/Git-Basics-Undoing-Things#_unstaging), tell me to use `git reset HEAD`.

I have no idea about the new `restore` command. I tried Google to find the difference between `git reset` and `git restore` but nothing seemed to fit my question.

What is the `git restore` command and what is the difference between `git restore` and `git reset`?

Chrome exhibits huge lags when viewing a given web page of mine. I&#39;m using the DevTools *Performance* tab to try and find the culprit which I assume to be somewhere in my JavaScript code.

The following screenshot shows a profile recorded using DevTools. For some of the &quot;tasks&quot; shown in the profile, I can see the details of what the tasks are doing (for example, the one between 8700 ms and 9200 ms is GC), but for other tasks there are no details whatsoever, like the two I have highlighted in the screenshot. How do I figure out what are those tasks doing?

My web client application is setting HTTP POST requests via fetch API. 

I see that OPTIONS preflight requests are sent via debugging proxy (Charles Proxy), but they are not displayed in Google Chrome Developer Tools\Network tab. 

I don&#39;t have any filters setup on the network tab. I remember OPTIONS requests being visible there, but not anymore. How do I bring them back?

Chrome 76 has added support for `prefers-color-scheme` media query (a.k.a. &quot;dark mode&quot;). 

But how can I test my webpage in both color schemes easily, without toggling the system dark mode on and off?

Here is the [same question](https://stackoverflow.com/questions/56401662/firefox-how-to-test-prefers-color-scheme) for Firefox, but I can&#39;t find similar settings in Chrome &amp; Chrome DevTools.

How can I emulate prefers-color-scheme media query in Chrome?

Is anybody else getting this Chrome console warning? 

&gt; A cookie associated with a cross-site resource at &lt;URL&gt; was set
&gt; without the `SameSite` attribute. A future release of Chrome will only
&gt; deliver cookies with cross-site requests if they are set with
&gt; `SameSite=None` and `Secure`. You can review cookies in developer
&gt; tools under Application&gt;Storage&gt;Cookies and see more details at &lt;URL&gt;
&gt; and &lt;URL&gt;.

In Chrome Flags chrome://flags/ I&#39;ve tried disabling both: 

 - SameSite by default cookies
   
 - Cookies without SameSite must be secure

And the warning won&#39;t go away. 


Chrome Console SameSite Cookie Attribute Warning

I&#39;m currently working on a website, which triggers a ```net::ERR_HTTP2_PROTOCOL_ERROR 200``` error on Google Chrome. I&#39;m not sure exactly what can provoke this error, I just noticed it pops out only when accessing the website in HTTPS. I can&#39;t be 100% sure it is related, but it looks like it prevents JavaScript to be executed properly.

For instance, the following scenario happens :

1. I&#39;m accessing the website in HTTPS

2. My Twitter feed integrated via https://publish.twitter.com  isn&#39;t loaded at all 

3. I can notice in the console the ERR_HTTP2_PROTOCOL_ERROR

4. If I remove the code to load the Twitter feed, the error remains

5. If I access the website in HTTP, the Twitter feed appears and the error disappears 

Google Chrome is the only web browser triggering the error: it works well on both Edge and Firefox.
(NB: I tried with Safari, and I have a similar ```kcferrordomaincfnetwork 303``` error)

I was wondering if it could be related to the header returned by the server since there is this &#39;200&#39; mention in the error, and a 404 / 500 page isn&#39;t triggering anything. 

Thing is the error isn&#39;t documented at all. Google search gives me very few results. Moreover, I noticed it appears on very recent Google Chrome releases; the error doesn&#39;t pop on v.64.X, but it does on v.75+ (regardless of the OS; I&#39;m working on Mac tho).

----------


Might be related to https://stackoverflow.com/questions/49927327/website-ok-on-firefox-but-not-on-safari-kcferrordomaincfnetwork-error-303-neit


----------


Findings from further investigations are the following:

 - **error doesn&#39;t pop on the exact same page if server returns 404 instead of 2XX**
 - error doesn&#39;t pop on local with a HTTPS certificate
 - error pops on a different server (both are OVH&#39;s), which uses a different certificate
 - error pops no matter what PHP version is used, from 5.6 to 7.3 (framework used : Cakephp 2.10)

As requested, below is the returned header for the failing ressource, which is the whole web page. Even if the error is triggering on each page having a HTTP header 200, those pages are always loading on client&#39;s browser, but sometimes an element is missing (in my exemple, the external Twitter feed). Every other asset on the Network tab has a success return, except the whole document itself.

A ```curl --head --http2``` request in console returns the following success:

```

Trying to go deeper with the chrome://net-export/ and https://netlog-viewer.appspot.com tools is telling me the request ends with a RST_STREAM :
```
t=123354 [st=5170]    HTTP2_SESSION_RECV_RST_STREAM
                      --&gt; error_code = &quot;2 (INTERNAL_ERROR)&quot;
                      --&gt; stream_id = 1
```
For what I read in [this other post][4], &quot;*In HTTP/2, if the client wants to abort the request, it sends a RST_STREAM. When the server receives a RST_STREAM, it will stop sending DATA frames to the client, thereby stopping the response (or the download). The connection is still usable for other requests, and requests/responses that were concurrent with the one that has been aborted may continue to progress.
[...]
It is possible that by the time the RST_STREAM travels from the client to the server, the whole content of the request is in transit and will arrive to the client, which will discard it. However, for large response contents, sending a RST_STREAM may have a good chance to arrive to the server before the whole response content is sent, and therefore will save bandwidth.*&quot;

The described behavior is the same as the one I can observe. But that would mean the browser is the culprit, and then I wouldn&#39;t understand why it happens on two identical pages with one having a 200 header and the other a 404 (same goes if I disable JS).

I rarely use HTML and JavaScript and almost forget the most fundamentals. What is the error?
