Use %40 in your username instead of the @ symbol for the url encoding.  It should pass it properly then.

Just do:

     http://my_email%40gmail.com:password@www.my_site.com

I am quite surprised that problem was with username `@` and not the password -usually this is where I get reserved characters in url authority or path parts. 

To solve general case of special characters: Just open chrome console with &lt;kbd&gt;F12&lt;/kbd&gt; then paste  `encodeURIComponent(str)` where `str` is your password (or username) and then use the encoded result to form url with password.

Hope this saves you some time.

I&#39;m using Android&#39;s `ViewPager`. What I want to do is to show a preview of the page on both the left and the right. I&#39;ve seen where I can use a negative `pageMargin` to show a preview of the right side.

    setPageMargin(-100);

Is there anyway that I can show a preview of the left side aswell? Its basically something similar to the gallery widget that I am looking for.

I have a dataframe and I would like to count the number of rows within each group. I reguarly use the `aggregate` function to sum data as follows:

    df2 &lt;- aggregate(x ~ Year + Month, data = df1, sum)

Now, I would like to count observations but can&#39;t seem to find the proper argument for `FUN`. Intuitively, I thought it would be as follows:

    df2 &lt;- aggregate(x ~ Year + Month, data = df1, count)

But, no such luck.

Any ideas?

Some toy data:

    df1 &lt;- data.frame(x = 1:20,

                      Month = sample(month.abb[1:3], 20, replace = TRUE))

To send username and password with a URL, we use this scheme:

    http://username:password@www.my_site.com

But my username is `my_email@gmail.com`.  
The problem is the `@`. 

How can I solve it?

What is the best way to parse data out of a URL query string (for instance, data appended to the URL by a form) in python?  My goal is to accept form data and display it on the same page.  I&#39;ve researched several methods that aren&#39;t quite what I&#39;m looking for. 

I&#39;m creating a simple web server with the goal of learning about sockets.  This web server won&#39;t be used for anything but testing purposes.

I was wondering, how do you close a connection with Requests (python-requests.org)? 

With `httplib` it&#39;s `HTTPConnection.close()`, but how do I do the same with Requests? 

Code:

    r = requests.post(&quot;https://stream.twitter.com/1/statuses/filter.json&quot;, data={&#39;track&#39;:toTrack}, auth=(&#39;username&#39;, &#39;passwd&#39;))
	for line in r.iter_lines():
		if line:
			self.mongo[&#39;db&#39;].tweets.insert(json.loads(line))

I read about _Pragma_ header on [Wikipedia](http://en.wikipedia.org/wiki/List_of_HTTP_header_fields) which says:

&gt; &quot;The Pragma: no-cache header field is an HTTP/1.0 header intended for
&gt; use in requests. It is a means for the browser to tell the server and
&gt; any intermediate caches that it wants a fresh version of the resource,
&gt; not for the server to tell the browser not to cache the resource. Some
&gt; user agents do pay attention to this header in responses, but the
&gt; HTTP/1.1 RFC specifically warns against relying on this behavior.&quot;

But I haven&#39;t understood what it does? What is the difference between the `Cache-Control` header whose value is `no-cache` and `Pragma` whose value is also `no-cache`?

Thanks to Google and Stack Overflow, I think I understood the difference between regular HTTP pipelining and HTTP multiplexing (e.g., with SPDY), so I made the diagram below to show the differences between pipelining and multiplexing based on three regular HTTP requests.

![enter image description here][2]


My two questions are:

 1. Is the image correct? 
 2. Is it true that if pipelining would not have the [head-of-line blocking problem][1] it would be as fast as HTTP multiplexing? Or did I miss an additional difference?

I&#39;ve had a look through existing questions, but I haven&#39;t really come across anything which works for me.

I&#39;m currently running a site with a Secure SSL certificate. It can be accessed at https://www.example.co.uk a problem is the site can also be accessed at http://www.example.co.uk - I don&#39;t want this to be possible. I need it to redirect from http to https.

I found this one snippet of code to use in an .htaccess file.

    Options +FollowSymLinks 
    RewriteEngine on 
    RewriteCond %{HTTP_HOST} ^example.co.uk [NC] 
    RewriteRule ^(.*)$ https://example.co.uk/$1 [L,R=301]

This works fine when the user enters example.co.uk into their address bar, but I also need to add a conditional statement of some sort so that if the user enters &#39;www.example.co.uk&#39; or &#39;http://www.example.co.uk&#39;. 

I&#39;ve tried using the likes of [OR], but this ends up creating server errors.

Any help and suggestions is appreciated.

Cheers.

Let&#39;s say my sample URL is

&gt; http://example.com/one/two

and I say I have the following route

    app.get(&#39;/one/two&#39;, function (req, res) {
        var url = req.url;
    }

The value of `url` will be `/one/two`.

How do I get the **full URL** in Express? 
For example, in the case above, I would like to receive `http://example.com/one/two`.

I&#39;m designing an HTTP-based API for an intranet app. I realize it&#39;s a pretty small concern in the grand scheme of things, but: **should I use hyphens, underscores, or camelCase to delimit words in the URIs?**

----------

Here are my initial thoughts:


**camelCase**

 - possible issues if server is case-insensitive
 - seems to have fairly widespread use in query string keys (http://api.example.com?**searchQuery**=...), but not in other URI parts

**Hyphen**

 - more aesthetically pleasing than the other alternatives
 - seems to be widely used in the path portion of the URI
 - never seen hyphenated query string key in the wild
 - *possibly* better for SEO (this may be a myth)


**Underscore**

 - potentially easier for programming languages to handle
 - several popular APIs (Facebook, Netflix, &lt;strike&gt;StackExchange&lt;/strike&gt;, etc.) are using underscores in all parts of the URI.

I&#39;m leaning towards underscores for everything. The fact that most of the big players are using them is compelling (see https://stackoverflow.com/a/608458/360570).

Hyphen, underscore, or camelCase as word delimiter in URIs?

I have my site on the server `http://www.myserver.uk.com`.

On this server I have two domains:

```lang-none
one.com and two.com
```

I would like to get the current domain using PHP, but if I use `$_SERVER[&#39;HTTP_HOST&#39;]` then it is showing me

```lang-none
myserver.uk.com
```

instead of:

```lang-none
one.com or two.com
```

How can I get the domain, and not the server name?

Is there a kind of URLEncode in Groovy?

I can&#39;t find any String → String URL encoding utility.

Example: `dehydrogenase (NADP+)` → `dehydrogenase%20(NADP%2b)`

&lt;i&gt;(`+` instead of `%20` would also be acceptable, as [some][1] implementations do that)&lt;/i&gt;

Passing a filename to the firefox browser causes it to replace spaces with `%2520`  instead of `%20`.

I have the following HTML in a file called `myhtml.html`:

    &lt;img src=&quot;C:\Documents and Settings\screenshots\Image01.png&quot;/&gt;

When I load `myhtml.html` into firefox, the image shows up as a broken image.  So I right click the link to view the picture and it shows this modified URL:

    file:///c:/Documents%2520and%2520Settings/screenshots/Image01.png
                        ^
                        ^-----Firefox changed my space to %2520.

What the heck?  It converted my space into a `%2520`.  Shouldn&#39;t it be converting it to a `%20`?  

**How do I change this HTML file so that the browser can find my image?  What&#39;s going on here?**

A html space is showing as %2520 instead of %20

When I copy a UTF-8 URL from the browser&#39;s address bar (almost any browser on any os), then try to paste it in another text field (to post it on facebook or twitter for example), it gives only the decoded URL, which makes it ugly. For example, in the address bar, the URL appears like this one:

 &gt; https://www.chaino.com/وذكر 

But when trying to copy and paste it in any other place, it gives the following ugly url:

 &gt; https://www.chaino.com/%D9%88%D8%B0%D9%83%D8%B1

&amp; if I wanted to get the original URL to use it in any place, I used to decode it in this [Raw URL Decoder - Online Tool][1] 

**Question is:** is there a short direct way to copy these kind of URLs, and paste it without this hideous process? (may be using chrome extensions or something)
