Google chrome sends multiple requests to fetch a page, and that's -apparently- not a bug, but a feature. And we as developers just have to deal with it.

As far as I could dig out in five minutes, chrome does that just to make the surfing faster, so if one connection gets lost, the second will take over.

I guess if the website is well developed, then it's functionality won't break by this, because multiple requests are just not new.

But I'm just not sure if I have accounted for all the situations this feature can produce.

Would there be any special situations? Any best practices to deal with them?

Update 1: Now I see why my bank's page throws an error when I open the page with chrome! It says: "Only one window of the browser should be open." That's their solution to security threats?!!

Your best bet is to follow standard web development best practises: don't change application state as a result of a GET call.

If you're worried I recommend updating your data layer unit tests for GET calls to be duplicated & ensure they return the same data.

(I'm not seeing this behaviour with Chrome 8.0.552.224, by the way, is very new?)

How to Fix a Google Chrome Sending Request, If there are multiple tabs, all of those pages get stuck, but after some time all the tabs start loading concurrently. There are a few things you can do to fix this  The ready function sends a POST request to commence an ajax conversion. This all works fine in Opera, FireFox,IE9, however Chrome keeps sending back an extra GET request after the initial (and all subsequent) POST requests. This extra GET totally breaks the conversation (and causes the page to reset in my case)

I saw the subjected behavior while writing a server application and found that earlier answers are probably not true.

Chrome distributes a single request into multiple http ones to fetch resources in parallel. In this case, it is an image which it fetches as a separate http get.

I have attached screen shot of packet capture through wireshark.

It is for a simple get request to port 8080 for which the server returns a hello message.

Chrome sends the second get request for obtaining favorite icon which you see on top of every tab opened. It is NOT a second get to cater time out or any such thing.

It should be considered another element that differs across browsers. However, doing things in multiple http requests in parallel is kind of a standard thing in browsers as of 2018.

Here is a reference question that i found latter

As long as you've got this panel open, you'll be able to see all the history of everything that was requested by your application and what the server sent in response to those requests.

It also can be caused by link tags with empty href attributes, at least in Chromium (v41). For example, each of the following line will generate an additional query on the page :

<link rel="shortcut icon" href="" />
<link rel="icon" type="image/x-icon" href="" />
<link rel="icon" type="image/png" href="" />

It seams that looking for empty attributes in the page is a good starting point, either href or src.

My observation of this characteristic (bug/feature/whatever) occurs when I am typing in a URL and the Autocomplete lands on a match while still typing in the URL. Chrome takes that match and fetches the page, I assume for the caching benefits that would occur when loading the page yourself....

double requests from Chrome, Does anyone know why Chrome is sending duplicate requests and what I can do to avoid this? -- R. Mark Volkmann Object Computing, Inc. In comparison, when I use curl and request the same page, I receive only one request. Same one request if I refresh the page in Safari. Why would Chrome send two requests for the same page? Edit: I've looked into the request.headers and found one difference: the accept header. Here is the header for the first request.

This behavior can be caused by SRC='' or SRC='#' in IMG or (as in my case) IFRAME tag. Replacing '#' with 'about:blank" has fixed the problem.
