ViewSource - View Source in Mobile Browsers

ViewSource Screenshot

Here's another small app that I created to play around with some code, but mostly because I felt I had a need for it.

ViewSource is an app for viewing the HTML-source of any website from your web-browser. Which enables you to view source from mobile browsers.

Just enter any URL and view the HTML-source. You also get a list of CSS-files and JavaScript-files, which you can view the source of, instantly in your browser.

You can quickly reach the app through

Fork on GitHub

As always, the source is available on GitHub for forking.

IIS URL Rewrite-Rules Skipping Files-types

IIS Welcome

If you need to put in a rule for the IIS URL Rewrite Module, but need the rule to skip some file-endings and/or targets that are directories or actual files on disk, this is the post for you.

Following some SEO best-practices that tells us to use trailing slashes on our URLs I used the IIS Manager and added the IIS URL Rewrite-module's built-in rule "Append or remove the trailing slash symbol", which creates the following rule:

 <rule name="Add trailing slash" stopProcessing="true">
  <match url="(.*[^/])$" />
    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
  <action type="Redirect" redirectType="Permanent" url="{R:1}/" />

This rule takes into account and doesn't apply the rule to files and directories that exists on disk. But there is a big problem with this generic rule.

If you are dynamically serving up files with extensions, then an URL like:

will become:

Adding conditions for specific file-endings

To solve this you can add conditions for certain file-endings, like .html and .aspx:

  <!-- ... -->
  <add input="{REQUEST_FILENAME}" pattern="(.*?)\.html$" negate="true" />
  <add input="{REQUEST_FILENAME}" pattern="(.*?)\.aspx$" negate="true" />

Since the rules above already don't apply for files physically on disk, you don't need to add file-endings like .css, .png or .js.

Update: Match ANY file-ending

If you want to match just any file-ending at all, you use the following pattern:

  <!-- ... -->
  <add input="{URL}" pattern=".*/[^.]*\.[\d\w]+$" negate="true" />
