2. Showing results in http://localhost/genie-works/devojp/customer/search-result?keyword=apple&searchcity=1 this page.

3. here listing too many business data with post an enquiry feature.

4. when clicking on the post an enquiry button page goes to http://localhost/genie-works/devojp/customer/post-enquiry/{bisinjessid}/

5. the post enquiry page checking a middle-ware as authentication.

6. when user not logged in the middleware redirect to login page http://localhost/genie-works/devojp/customer and showing the login form

7. after entering login details its needs to redirect to http://localhost/genie-works/devojp/customer/post-enquiry/{bisinjessid}/ this page.

8. but i tried the function Redirect::back its redirecting to customers page (http://localhost/genie-works/devojp/customer)

   How can i solve this issue by redirecting to my last page....
