The XML Sitemap Generator I have installed will not crawl pages with Apache redirects. Two of the largest sections of my site rely on such redirects.
To recreate, try mapping
[external links are visible to admins only]
[external links are visible to admins only]
If you visit these URLs in the browser, you will see that they point to [external links are visible to admins only] and [external links are visible to admins only] respectively.
Why won't the script honor this? I do not think it is an installation issue because the free sitemap generator will not follow these URLs either. Is there a known workaround for this limitation, or any plans to fix it?
