Authentication not working

> ==Tips and advice==
> ===Check the logs===
> Check the ##hts-log.txt## and ##hts-err.txt## error log files generated in your project's directory by HTTrack -- this may give you important information
> ===Create a small test first===
> Plan ahead of time. If you know you are going to use authentication, create a small HTTrack project just to test that HTTrack is able to successfully login.
> There are a couple of ways to easily do that, and basically you want to exclude all the website's pages/files and just allow the "login" page and the "logged in" page.
> **For example:**
> Set the start URL: http://example.com/clients/login.php
> Filters: ##-*## ##+*/clients/welcome.php*##
> ===Exclude logout pages===
> Remember to exclude any "logout" pages on the site you are mirroring! It would be no good if you've made HTTrack authenticate but then it finds the log-out page and ruins your project.
> See our help page about [[Filters]]. You'll probably use a filter like ##-*/logout.jsp##
> ===Beware cookies.txt===
> If you reuse an existing project (e.g. update an existing project, or re-run a project when you are trying to get authentication to work) you may experience problems related to cookies.
> If you are having trouble making HTTrack authenticate, check for a ##cookies.txt## file in your project's folder and delete it before running the project again.
