I have an embedable widget. For each impression, I would like to track the referrer (the page where the widget is embedded onto). Right now I am using ExternalInterface to use javascript to check window.location.href when its available, however, I am finding that most of the time I am unable to set the referrer.
Is there a better way to do this? Or perhaps am I not using javascript correctly to get the referrer?
Thanks!
I don't think you can directly get it in this way. There are a couple options I can think of:
Get the referrer from your web server HTTP logs. Apache for example logs referrer info by default.
Have people include some referral code in their widget request, that you can use to identify where it came from.
Make a request from your widget back to your server...I think this request will contain the HTTP Referrer field pointing at where it is embedded
Use something like [swfmill][1] to embed the referrer into the actual SWF itself when it is requested from your server...but this might have too much performance overhead.

Is there a way to only show a clean url when doing a get request?
i.e. someone is send to a page:
http://domain.com/?param1=1¶m2=2
And the user only sees :
http://domain.com
I tried it with a post-request but then you get these annoying pop-ups when someone refreshes the page or hits the back button.
Doing a post-redirect-get is also not possible since this increases the response time to much and the page is generated dynamically so it needs the parameters.
You could use URL rewriting when you are using Apache.
Or similar functionalities in other web servers.
There are 3 ways to pass parameters from a client to a server:
GET request; which you don't want to use
POST body (includes post-redirect-get); you don't wan to use POST
request header
The way to have a client pass arbitrary parameters in a request header is cookies.
When making an HTTP request (using URLLoader, for example) that results in a redirect, is it possible to access any of the URLs in the redirect chain?
For example, let's say that the following happens:
We make a request to example.com/a.gif
example.com redirects to example2.com/b.gif
example2.com redirects to example3.com/c.gif
I've stared at the documentation for URLLoader and its various events for a while, and it doesn't seem like there's a way to either:
Instruct URLLoader to not follow redirects
Access any of the URLs involved after the initial request
Does anyone know if there's a way to do this? I'm not attached to using URLLoader, so if there's another class that supports this functionality, I'd be fine with using it.
Can anyone point me in the right direction? Thanks in advance!
Edit - I should clarify: I know how to detect the redirects outside of AS3 using a DOM debugger. I'm specifically interested in accessing the redirect chain within AS3. It would appear that it's possible using the AIR player via the HttpStatusEvent, but the relevant properties aren't available when using Flash Player.
Edit 2 - I've also tried using an HTTP client lib (as3httpclientlib, to be specific). This works except for the fact that it loads cross-domain policies from port 843 rather than by making an HTTP request to /crossdomain.xml. The context I'm working in requires the latter, so using something with Socket underlying it won't work unless there's a way to force Socket to load cross-domain policies from HTTP instead of port 843.
The redirects are generally in place because the original URL shouldn't be used anymore. The file doesn't exist at example.com/a.gif so in theory you don't need to know about it. Why do you need the intermediate request path?
I'm not aware of an actionscript way of finding the redirect chain for any request, but if you want to do it for a specific chain you can use HttpFox for Firefox, or hit f12 in google chrome and look at the network tab when making a request to the URL that redirects. This will only work if the client is redirected by the server to the new address (a HTTP 302 responce or similar.) If the server chooses to return the contents of example3.com/c.gif when someone's browser asks for example.com/a.gif there is nothing you can do.
I want to make a turn based game (Something like Checkers) with the help of Servlets and jsp pages.I created a page that has a newGame button that redircet to the gamePage(It redirect the first into a Black.jsp and the other request will be redirected to Red.jsp).
My problem is ,how could I refresh the other jsp automaticaly if one of them changed.
Note:After the change in one of the jsp it redirect the request to servlet and servlet update the changed jsp graphics.but the other jsp stay inactive.I want to make it active.
Thank You
It sounds like what you need is Comet. Here's an overview of how it works.
http://www.ibm.com/developerworks/web/library/wa-cometjava/
Basically, the "other" user's browser will send a request to a servlet to get an update, but that request won't receive receive its response until the current player makes a move. This gets around the problem posed by the fact that, with traditional HTTP, the browser always has to be the one sending the request to the server, it can't be the other way around.
There are some variations on the technique. Now that you know the name, I'm sure you'll be able to find lots of useful information about it.
There's another technology called WebSocket which can also serve this purpose, but it requires additional capability built into the browser and, as of now, probably not all of your users will be using compatible browsers.
Im wondering if there is anyway to get scores from a gamecast that uses javascript or flash to update the content dynamically. Here's an example: http://www.cstv.com/gametracker/launch/gt_wlacros.html?sport=wlacros&camefrom=&startschool=md&event=952412&school=cs&
How could I pull the scores from the teams out of this page?
Really what you need to do is sniff the requests being made under the hood. You can get any sort of HTTP sniffer. I use Live HTTP Headers extension for firefox. You start capturing, then click the link above. You'll see all sorts of requests. The underlying data seems to be coming from http://origin.livestats.www.cstv.com. I got this request that has a lot of useful player stats from the game:
http://origin.livestats.www.cstv.com/livestats/data/w-lacros/952412/player_stats.xml?344026907808
http://origin.livestats.www.cstv.com/livestats/data/w-lacros/952412/summary.xml?644493847800
(note the second url throws an XML parse error, but you could still try to parse it manually)
I'm no expert on web development, and need to find a way to let the browser call a PHP routine on the server with the current document ID as parameter, eg.
http://www.acme.com/index.php?id=1
I then need to call eg. /change.php with id=1 to do something about that document.
Unless I'm mistaken, there are three ways for the client to return this information:
if passed as argument in the URL (as above), it will be available as HTTP referrer
by including it as hidden field in
by sending it as cookie
I suppose using a hidden field is the most obvious choice. Are there other ways? Which solution would you recommend? Any security issues to be aware?
Thank you.
You can also POST the data so it won't be seen in the URL with ’form method = "post" ’
All of these methods are, to a point, insecure as they can be manipulated by a savvy user/hacker. You could https your site, limiting any man in then middle attacks. Be sure to check and validate incoming data
Ajax is another option as well, and it allows you to send that information without refreshing the page.
http://www.acme.com/index.php?id=1
The above url would be more "browser friendly" if you transform it into something similar to this:
http://www.acme.com/index/page/1
I am sure you can achieve this in Apache. Or Java Servlets.
