How to Mask URLs

I need to know how to mask the URL that displays in the browser window on certain pages of my web site. My domain is parked, forwarded and masked at GoDaddy.com. The masking feature provided by [login to view URL] works fine on the sales page, payment pages ([login to view URL]), order confirmation page and download page. However, when users click on the links on the download page to download the pdf pages they have paid for, new browser windows open and the URL to the pdf files are displayed. I want to be able to mask these URLs to the pdf files. It is important that new windows open when the links to the pdf files are clicked. I build my web pages using Adobe GoLive 6.0 and have an elementary understanding of HTML. If the masking I require can be accomplished by adding special code to the pages I want to mask, I will need the code to install along with complete installation instructions. If the masking is more difficult to accomplish, I will need a coder to install it on my site. Either of these solutions should be fairly simple for someone who knows what they're doing! Please quotes for (1) providing the code with installation instructions and (2) installing the code yourself. A total of 4 pages need to be masked. I will pay using a preferred payment method. ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details.
