Crawl HTTPS Websites with A1 Website Analyzer

A1 Website Analyzer allows the user to select a HTTP solution in Scan website | Crawler engine.

The default setting is Auto detect which translates to:

• Windows: The setting HTTP using Windows API
• Mac: The setting HTTP using Mac API

It is also possible to select HTTP using Indy library which is an alternative solution.

Tip: If you have problems getting crawling working, be sure to check if A1 Website Analyzer is getting blocked by firewalls or similar solutions.

Note: This section is only necessary if:

1. Your website uses HTTPS.
2. You use Indy in Scan website | Crawler engine.

Configuring OpenSSL / Configuring LibreSSL for use with A1 Website Analyzer will help for all HTTPS / SSL based websites.

To add support for this, see General options and tools | Tool paths.



Clicking the button at the right will show a menu with information and links.

In newer versions of A1 Website Analyzer the menu will also show which version you should download for your computer system.

While this will usually work out of the box, you may sometimes need to do some configuration, especially on older systems
