Think about what your rewrite rules mean. They are saying: if /folder1 or /folder2 appears anywhere in the URI, stick drupal/ onto the front.

So say somebody goes to /folder1/page. Apache rewrites that to /drupal/folder1/page (assuming your RewriteBase is /), then it does an internal redirect. So now Apache has got the URI /drupal/folder1/page. Apache rewrites that to /drupal/drupal/folder1/page, then it does an internal redirect. And so on.... Apache gives up after a set of number of internal redirects. Read more »

Terminating contracts with IT vendors

Posted Thu, 07/10/2008 - 11:05 by donmc

What is going on these days ?

In the last week I have entered into projects with two separate customers who have been terrorized (the customer's wording, in one case) by their existing IT vendor, and want to find a new provider who won't attack them...

I find it hard to think with.

I have been told stories that demonstrate extremely poor character being played out in cases where the IT vendor has had a long-term (more than 1 year) relationship in place. One customer put it this way: "familiarity breeds contempt". Read more »
