I am using Google Maps JavaScript API in my website to display maps of various locations.
Based on online info and a couple of relevant posts on SO, the API is not supposed to create any cookies when called.
However, I have noticed that once in a while, just when rendering a map, I get two additional cookies in my browser: 1P_JAR & CONSENT (both from the domain gstatic.com).
Whenever I delete the cookies they won't come back for a while even after numerous renditions of maps.
As a source for the Maps API I am using https://maps.googleapis.com/maps/api/js?key=XXXXXX.
It seems then that I am wrong believing that the API would not create any cookies. Could somenone confirm? And most importantly, is there a way to avoid those cookies being created in my website?
Thanks

I'm not sure if this is the right stack to ask this in so if not please let me know!
I am trying to get a handle on what cookies are used on a site and what they are for. When I initially did a cookie scan I noticed a cookie names NID which was set by google.
I have tried to research this cookie and can see it is used by Google for advertising purposes.
But I am confused about why and where this is being set, the site I am looking at does not use advertising anywhere, although it does use embedded YouTube videos.
Can anyone shed any light on when and why this cookie is set?
according to Google
Most Google users will have a preferences cookie called ‘NID’ in their browsers. A browser sends this cookie with requests to Google’s sites. The NID cookie contains a unique ID Google uses to remember your preferences and other information, such as your preferred language (e.g. English), how many search results you wish to have shown per page (e.g. 10 or 20), and whether or not you wish to have Google’s SafeSearch filter turned on.
For me, the cookie was hammered incessantly by the url https://www.google.com/s2/favicons?domain=example.org Which was being used by CookieBro & FeedBro RSS feeder browser addons for retrieving icons associated with various domains. The cookie can be dropped by either an addon or by google itself.
I used cookie log via cookiebro addon for firefox & chrome to detect these cookies in realtime, its one of a kind. However I did not realize it was cookiebro dropping them until the next step below.
To see what background connection is occuring when these cookies are placed, enter the following firefox url: about:cache?storage=disk&context= and you will see when and where the google url being connected to.
It is said this cookie is for targeting & ADS and the google's settings are integrated to make the cookie inconvenient to delete for Google users.
I'm currently using a Google Maps embed on my website like this.
It shows me the correct position as well as raitings, opening hours and so on.
The only problem I have is that it places some cookies which I am not allowed to use (EU law, it would require some specific informations I do not want to display).
I already read some threads where people advised to use Google Maps API V3 but I can't figure out how to display the exact same informations like icon, raiting.
Is there any way to remove those cookies using the iframe method?
I work for an e-commerce site. Part of what we do is to offer customized items to some clients. Recently some non-technical management promised that we could incorporate our check-out process into one such client's website. The only way we've figured out how to do this is by using an iframe (I know, I don't like it either). The issue is that most customers of this site are unable to check out because we use cookies to determine which custom items to display. Browsers are recognizing our cookies as third party and almost everybody has third party cookies turned off, as they should. I'm going to be shocked if the answer is yes, but is there any workaround for this? ie can the site hosting our iframe somehow supply the necessary cookie?
Try an invisible, interstitial page.
Essentially the hosting site would issue a redirect to a site within your domain, which is then free to set cookies (because at this point is is actually the first party). Then your site immediately redirects back to the hosting site. At this point your newly-created cookies will be invisible to the hosting site but visible to your iFramed page henceforth.
Unfortunately the hosting site will have to do this every time a cookie is to be updated but the double-redirect can happen so quickly they'll hardly notice. Hopefully your system only needs the cookies to be set once.
Instead of using a cookie, pass the information in the each url request as name/value pairs.
It is a bit of a pain to add the name/value to every url...I know...oh well...it will work.

Your iframed page itself, which is the third party in this scenario, could send a P3P Cookie Policy header – some browsers then accept third-party cookies by default, whereas others (mainly Safari) will not be convinced to do so at all if not by the user manipulating the default settings themselves.
What you could also do, is pass the session id not (only) by cookie, but as a GET or POST parameter as well – f.e. under PHP this can be done quite easily by configuring the session options. You should consider if that’s worth the slightly increased risk of session stealing.
The interstitial page solution should work but it might be a lot of trouble for your hosting site, so here's another solution that will allow you to work cookieless.
Write an HttpModule that responds to the BeginRequest event, reads the querystring, and inserts corresponding cookie headers into the Context.HttpRequest object (Note: you can't use AddCookie, you have to use AddHeader, because cookies added by a module directly are disposed of before they hit your application proper). That way the hosting site can simply issue a request (within the iFrame) that contains the necessary value in the querystring, the module will convert it into a cookie (that only exists in memory, not on the wire), and your application will be deceived into thinking that there's a cookie there. No code changes required, you just need to add the module in web.config.
This only works if you are using IIS 7.0+ in integrated pipeline mode. If you're on an earlier version of IIS or if you have to run in classic mode, you'll need an ISAPI filter instead.

For the Chrome v80 update with SameSite flags, want to set the samesite=none;secure for the site hosting our iframe and somehow supply the necessary samesite=none;secure cookie. We have apache 2.2 and tomcat 6 setup, so would appreciate a solution and advice on how to make it work. Currently with flag enabled the iFrame is not punching out successfully.
Thanks
I am trying to build an application with ColdFusion.
I've been reading documentation and trying things out for days and for the life of my I can't seem to figure out how to display my own data to users from Google's APIs using OAuth2.
For example, I want to be able to display some of my stats to users with the Google Analytics API. How many unique hits, page views my site gets and from what countries. The data is private, however, so there isn't a way to do so. Or YouTube just changed their API so video tags can no longer be seen unless logged in. I want to be able to show my video tags so they can search for related things on my own site, but I can't pull them because I'm unsure of how to do this.
I know how to display and manipulate public data, but when it comes to private data, I'm at a complete loss. OAuth2 is kicking my butt!
Is there anybody that can please, please help me with OAuth2 so that I can allow my users to see my private Google data without there being any kind of log in process for them? Examples using ColdFusion would be so much appreciated.
The answer is more or less what I said at How to retrieve my own private playlist through YouTube API?
You'd want to use the OAuth 2 for Installed Applications flow, and generate new access tokens via your refresh token when your old access token expires. I'm not familiar with any libraries for doing OAuth 2 in Cold Fusion, though.
As the title implies,
I need to fetch data from certain website which need logins to use.
The login procedure might need cookies, or sessions.
Do I need QtWebkit, or can I get away with just QNetworkAccessManager?
I have no experience at both, and will start learning as I go.
So please save me a bit of time of comparing both ^^
Thank you in advance,
Evan
Edit: Having read some related answers,
I'll add some clarifications:
The website in concern does not have an API. So I will need to scrape web elements for the data myself.
Can I do that with just QNetworkAccessManager?
No, in most cases you don't need a full simulated web browser. In most cases, just performing the same web requests like a web browser would do is enough.
Try to record the web requests in your browser, using a plugin like "HTTP Live Headers" or "Firebug" in Firefox. I think Chrome provides a similar tool out of the box. These tools record the GET and POST requests done by the website when you send a form in the webpage.
Another option is to inspect the HTML code of the login page. Find the <form> tag and its fields. Put them together in a GET / POST request in your application to simulate the same form.
Remember that some pages use randomized "tokens" in their forms, some set the tokens as cookies. In such cases, you need to request the login page itself in your application first (before sending the filled in form). Both QWebView and QNetworkAccessManager have cookie support.
To sum things up, I think QWebView provides a far more elegant way to simulate user interaction with a web page. The manual way is, however, more "lightweight", as you don't need Webkit and your application might be faster (because only the HTML page is loaded, without any linked resources like images, CSS, javascript files).
QWebView as class name states is a view, so it views something (in this case web pages). If you don't need to display loaded page, then you don't need a view. QNetworkAccessManager may do the work, but you need some knowledge about HTTP protocol, and also anything about target site: how does it hande logins, what type of request you have to send to login etc.
