Root-Relative Paths (~/path) in Web Connection
Root relative paths allow you to create location independent urls that work regardless from where within the application they are called. This means you can use a url with root-relative path syntax and get consistent results in any directory of the application which makes the url portable – easy to copy and/or use in other pages without changes. Web Connection supports root-relative paths in various ways. Here’s how. |

A few Thoughts on Web Connection and Security
Security is an important topic that's unfortunately addressed way too late in the development process many times. I can attest to that personally.

COM Interop and .NET Guids
Guid values in .NET are unfortunately not directly accessible in VFP via COM interop because the type is not marshalled in a meaningful way over COM for VFP to consume. You get an error when trying to access a Guid value. This is a common problem for Value types marshalled over COM. In this post I'll describe a way around this by way of an intermediary function to intercept method calls and convert parameters and return values into something that can be consumed in FoxPro. |

Header Manipulation in the Web Control Framework
Header access via is currently not supported in the Web Connection Web Control Framework, but that doesn't mean that you can't manipulate the header fairly easily. Using Expressions is one way that works today. In the next update there will also be an explicit Header object that allows dynamically adding content to the header that the top or bottom more easily. |
