[Fixed]-Regex to accept anything in url django

Your regex basically says

 reply/something here/   

or
reply//

Hence the reason that you are getting the redirect. Easiest thing is probablly to use two url patterns here or

url(ur'^reply/(.*)/?$', views.visit),

But the above has the undesirable side effect of links without trailing slashes not being directed to the version with the trailing slash

Those inputs are get parameters, and you don’t need to match them in a url – if anything matching them in a url would make it harder for yourself since you’d then need to parse them in a view yourself.

Instead just change your url to just the /reply/ and lookup all the get parameters in the request.GET dictionary in the view

url(ur'^reply/$', views.visit),

dev visit(request):
    anything = request.GET['input']
    agent_type = request.GET.get('agent_type')
