Note to self: This seems to work - even with danish date formats:
If you have one application on your IIS and several domain names pointing to it, it’s possible to have different robots.txt files served based on the current domain name.
1. Add a route
2. Create the RobotsController
3. The SeoHelper just implements a simple way of determine what robots.txt file to return
4. Add the different versions of the robot.txt to the site root – remark the content for the robots.txt could be served from any source, I have just chosen a simple model to keep it simple
5. Run the site and request robots.txt
Get the source code: DynamicRobotsTxt.rar (21,66 kb)

Just for the record
An asp:ImageButton without image won’t fire its events in Firefox
Remember this and save yourself an hour: always attach an image to your asp:ImageButton
I just had one of those WOW experience today when I happened to use the switch code snippet with an enum.
I had an enum like this:
1: enum MyEnum
Start the video to se what happened when I tapped out of the snippet "switch_on" field.
WOW the snippet automatically created:
for each element in the enum. But how did it do that? Looking into the switch.snippet file I found:
It's the GenerateSwitchCases function that's doing the job - one out of 3 pre defined functions that available to "snippets"
I don’t know about you but I for my part often end out writing linear code.
Maybe it’s a hangover from writing to much BASIC code in the mid 80’s or maybe it’s just me thinking linear and not that much object-oriented. After all I often end up with “long functions” that includes code that could be isolated in “sub functions”.
Today one of my colleges pointed out the Refactor->Extract Method function. This function takes a part of your code and isolate it’s in a separate function.
Look at the code in this Page_Load: its includes some silly greeting stuff (just for the demo), the function is long and hard to read, lets try to separate the greetings part in a separate function.
Highlight the code you want to move to a new function, right click and select Refactor -> Extract Metod.
Give the function a nice name (getGreeting). Notice the signature preview show what parameters the function will be created with.
The Page_Load after generating the getGreeting function - nice and easy to read ;-)
The auto generated function takes 2 parameters and return a string
