how to create a static html page which will be displayed when the app is up and replace it during pl

Hi,
I have asked this question previously, and saw that Kartheek asked a similar question.

It would be nice to combine the 2 questions:

 

 Question1 – how to handle very long URL

Question2 -  Replace the URL during planned maintenance

 

My url that comes from the ear file is very long, and I handled that by using redirect in httpd.conf; not very elegant but it works for now.

 

Now reading the post by Vijaya on Kartheek’s question (bellow), I am getting different ideas:

If I can do what Vijaya suggests, and during planned maintenance, replace the html page with a different html file, static page to inform users the system is down.
