Highlight of my workday was debugging an issue that turned out to be nothing like what the reporter had diagnosed. It wasn’t until I took a deep dive into the logs that I realised that this was a secondary characteristic of many URLs found in customers’ SharePoint installations. And SharePoint often uses relative URLs when it sends redirections. And it turned out that our systems’ redirect handler… wasn’t correctly handling relative URLs. It all turned into a hundred line automated test to mock SharePoint and demonstrate the problem… followed by a tiny two-line fix to the actual code.
