ASP.Net Page layout is not displaying properly in QA machine but is displaying correctly in Dev Machine

ASP.Net Page layout is not display开发者_JS百科ing properly in QA machine but is displaying correctly in Dev Machine. What could be the issue? We are using ASP.Net 2.0

Very common issues are:

• QA machine still has old resources in the browser cache

  IE: Hit CTRL + Refresh
  FF, Chrome: SHIFT + Refresh

• Resource Paths are different.

  Somewhere a path to an image starts with "/" which relates to to absolute route of a page.
  On the dev machine the page is: localhost:8080/default.aspx
  On the QA its: localhost:8080/somepath/default.aspx

  This will not work anymore, replace the absolute paths or make sure the path depth is the same everywhere
