<p>A common argument against using .NET for high volume, transactional enterprise systems is that IIS does not compare to the likes of Weblogic and websphere for java. Is this true? Unfortunately for .NET web apps IIS is the only option as an application server. Does anyone have any arguments against this? I would like... | <p>I've been coding ASP.NET for 6 years now and prior to getting into the field I was a network engineer. IMO, ASP.NET on IIS is faster out of the box than most of those other platforms. However, it's easy to screw up performance with mediocre programming skills, and it is possible that a highly tuned platform could be... | <p>Actually, running ASP.NET on Mono/Apache is starting to become popular.</p>
<p>Personally I stick to IIS because that's what I know, but if you are already a Linux shop I would recommend Mono without hesitation.</p>

<p>Our project uses Cruise Control to both build and hot deploy a web application to a remote server (via FTP) running Tomcat in the form of a .war file.

<p>I am familiar with inserting text nodes after or before a given reference node. But, I would like to know how to insert a tag between text in a given node. For example, </p>

Body = (string)element.Element("Body")

<p>I'd like to call caspol from within a script inside a custom action in
an msi (setup project). I'd prefer a standard msi to ClickOnce,

filetypes with our application whereas with ClickOnce I can't.</p>

<p>If you copy your texts to an empty file, it formats it the way you want it. I have smartindent and autoindent enabled, so you could try that. (set si, set ai)</p>
| <p>I had the same problem. I looked at my settings like this:</p>
<p>:set</p>
<p>I didn't have cindent set, but I did have smartindent. So, based on the above:</p>
<p>:set nosmartindent</p>
<p>Then the unwanted indentation on the last line (just as described above) was fixed. </p>
<p>Thanks for the help!</p>
