As I understand it, you try to use IE because if automatically sends your credentials (or maybe you didn't know of any other option).

Why the above answers don't work is because you try to download file from SharePoint and you send an unauthenticated request. The response is 401.

This works:

<pre><code>PS&gt;$wc=new-object system.net.webclient
PS&gt;$wc.UseDefaultCredentials = $true
PS&gt;$wc.downloadfile("your_url","your_file")
</code></pre>

if the the current user of Posh has rights to download the file (is the same as the logged one in IE).

If not, try this:

<pre><code>PS&gt;$wc=new-object system.net.webclient
PS&gt;$wc.Credentials = Get-Credential
PS&gt;$wc.downloadfile("your_url","your_file")
</code></pre>

Update Jan 2014: With Powershell v3, released with Windows 8, you can do this:

<pre><code> (Invoke-webrequest -URI "http://www.kernel.org").Content
</code></pre>

Original Post, valid for Powershell Version 2

This solution is very similar to the other answers from stej, Jay Bazusi and Marco Shaw.
It is a bit more general, by installing a new module into your module directory, psurl. The module psurl adds new commands in case you have to do a lot of html-fetching (and POSTing) with powershell.

<pre><code>(new-object Net.WebClient).DownloadString("http://psget.net/GetPsGet.ps1") | iex
</code></pre>

See the homepage of the code-sharing website <a href="http://psget.net/">http://psget.net/</a>.

<blockquote>
 This nice line of PowerShell script will dowload GetPsGet.ps1 and send
 it to Invoke-Expression to install PsGet Module.
</blockquote>

Then install PsUrl, a Powershell Module inspired by curl:

To install something (in our case PsUrl) from central directory just type:

<pre><code>install-module PsUrl

get-module -name psurl
</code></pre>

Output: 

<pre><code>ModuleType Name ExportedCommands
---------- ---- ----------------
Script psurl {Get-Url, Send-WebContent, Write-Url, Get-WebContent}
</code></pre>

Command:

<pre><code>get-command -module psurl
</code></pre>

Output: 

<pre><code>CommandType Name Definition
----------- ---- ----------
Function Get-Url ...
Function Get-WebContent ...
Alias gwc Get-WebContent
Function Send-WebContent ...
Alias swc Send-WebContent
Function Write-Url ...
</code></pre>

You need to do this only once.

Note that this error might occur:

Q: Error "File xxx cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details."

A: By default, PowerShell restricts execution of all scripts. This is all about security. To "fix" this run PowerShell as Administrator and call

<pre><code>Set-ExecutionPolicy RemoteSigned
</code></pre>

From now on, in your new powershell sessions/scripts, do this: 

<pre><code>import-module psurl
get-url "http://www.google.com"
</code></pre>

To download and save to a file, do this:

<pre><code>get-url "http://www.google.com" | out-file -filepath "myfile.html"
</code></pre>

If you're truly only concerned with the raw string content, the best route, as mentioned by a few others, is using the constructs within .NET to do this. However, I think in the previous answers a few opportunities are missed.

<ul>
<li>It's often best to <a href="https://stackoverflow.com/a/1694400/2421277">use</a> <code>WebRequest</code> over <code>WebClient</code> as it provides better control over the entire request cycle</li>
<li>Response buffering via <code>System.IO.StreamReader</code>, made possible by using <code>WebRequest</code></li>
<li>Creating a testable, reusable tool. Which is the very nature and purpose of PowerShell</li>
</ul>

<pre class="lang-bsh prettyprint-override"><code>function Get-UrlContent {
 &lt;#
 .SYNOPSIS

I am working in a script, where I am able to browse the web content or the 'url' but I am not able to copy the web content in it &amp; download as a file.
This is what I have made so far:
<pre><code>$url = &quot;http://sp-fin/sites/arindam-sites/_layouts/xlviewer.aspx?listguid={05DA1D91-F934-4419-8AEF-B297DB81A31D}&amp;itemid=4&amp;DefaultItemOpen=1&quot;
$ie=new-object -com internetexplorer.application
$ie.visible=$true
$ie.navigate($url)
while($ie.busy) {start-sleep 1} 
</code></pre>
How can I copy the content of <code>$url</code> and save it to local drive as a file?
<h3>Update:</h3>
I got these errors:
<blockquote>
Exception calling &quot;DownloadFile&quot; with &quot;2&quot; argument(s): &quot;The remote server returned an error: (401) Unauthorized.&quot; At :line:6 char:47 + (New-Object system.net.webclient).DownloadFile( &lt;&lt;&lt;&lt; &quot;$url/download-url-content&quot;, 'save.html' )

Ok, let me explain more, on what I am trying to do: I have a excel file in our share point site &amp; this is the file I am trying to download locally(any format), which is a part of the script, so that for the later part of the script, I can compare this file with other data &amp; get an output.
Now if I can somehow map &quot;my documents&quot; from the site &amp; able to download the file, that will also work for me.
