I want to mask a url name in addressbar. I don't know how to do it. I have two domains. www.domainA.com and www.domainB.com. When user goes to www.domainB.com/subdirectory, he should redirect to www.domainA.com/subdirectory, but in address bar it should be www.domainB.com/subdirectory.
Now i have redirected the url from www.domainB.com/subdirectory to www.domainA.com/subdirectory, but it shows www.domainA.com/subdirectory, instead of www.domainB.com/subdirectory
How to mask it, please suggest
