How would I have a JavaScript action that may have some effects on the current page but would also change the URL in the browser so if the user hits reload or bookmark the new URL is used?
It would also be nice if the back button would reload the original URL.
I am trying to record JavaScript state in the URL.

In my project I need the Google cache age to be added as important information. I tried to search sources for the Google cache age, that is, the number of days since Google last re-indexed the page listed.
Where can I get the Google cache age?

How do you encode a URL in Android?
I thought it was like this:
final String encodedURL = URLEncoder.encode(urlAsString, "UTF-8");
URL url = new URL(encodedURL);
If I do the above, the http:// in urlAsString is replaced by http%3A%2F%2F in encodedURL and then I get a java.net.MalformedURLException when I use the URL.

Path.Combine is handy, but is there a similar function in the .NET framework for URLs?
I'm looking for syntax like this:
Url.Combine("http://MyUrl.com/", "/Images/Image.jpg")
which would return:
"http://MyUrl.com/Images/Image.jpg"

How to open an URL from code in the built-in web browser rather than within my application?
I tried this:
try {
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(download_link));
startActivity(myIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "No application can handle this request."
+ " Please install a webbrowser", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
but I got an Exception:
No activity found to handle Intent{action=android.intent.action.VIEW data =www.google.com

Is there any way I can modify the URL of the current page without reloading the page?
I would like to access the portion before the # hash if possible.
I only need to change the portion after the domain, so its not like I'm violating cross-domain policies.
window.location.href = "www.mysite.com/page2.php"; // sadly this reloads

I am currently defining regular expressions in order to capture parameters in a url, as described in the tutorial. How do I access parameters from the url as part the HttpRequest object? My HttpRequest.GET currently returns an empty QueryDict object.
I'd like to learn how to do this without a library so I can get to know Django better.

I have a repo (origin) on a USB key that I cloned on my hard drive (local). I moved "origin" to a NAS and successfully tested cloning it from here.
I would like to know if I can change the URI of "origin" in the settings of "local" so it will now pull from the NAS, and not from the USB key.
For now, I can see two solutions:
push everything to the usb-orign, and copy it to the NAS again (implies a lot of work due to new commits to nas-origin);
add a new remote to "local" and delete the old one (I fear I'll break my history).

How do I get the website URL?
Not the URL as taken from a link. On the loading page, I want to get the full, current URL of the current web page and store its value in a variable.

How can I check if a given string is a valid URL address?
My knowledge of regular expressions is basic and doesn't allow me to choose from the hundreds of regular expressions I've already seen on the web.

I have a URL with a parameter as follows,
www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5
I need to get the whole value of c. I tried to read the URL, but I got only m2. How do I do this using JavaScript?

I've just noticed that the long, convoluted Facebook URLs that we're used to now look like this:
http://www.facebook.com/example.profile#!/pages/Another-Page/123456789012345
As far as I can recall, earlier this year it was just a normal URL-fragment-like string (starting with #), without the exclamation mark. But now it's a shebang or hashbang (#!), which I've previously only seen in shell scripts and Perl scripts.
The new Twitter URLs now also feature the #! symbols. A Twitter profile URL, for example, now looks like this:
http://twitter.com/#!/BoltClock
Does #! now play some special role in URLs, like for a certain Ajax framework or something since the new Facebook and Twitter interfaces are now largely Ajaxified? Would using this in my URLs benefit my Web application in any way?
