HttpPlatformHandler was created by Microsoft Azure team and made publicly available in 2015. More history about this Microsoft product can be found in this blog post.
As Microsoft didn't publish any new release after v1.2 and more issues related to this old release were reported by users, there is a need to give the user community something new. Our team at LeXtudio Inc. are experienced .NET developers with extensive IIS knowledge so we decided to give this a try.
We chose to fork and build upon ASP.NET Core module, which was initially a fork of HttpPlatformHandler itself, now is both open-source and well maintained by Microsoft ASP.NET Core team. By renaming many things through the code base, we are able to derive a slim module that just works for any programming languages/application servers. And most importantly we keep this new module backward compatible with HttpPlatformHandler v1.2. We used to call this project "HttpPlatformHandler v2" but now prefer to rename it to "HTTP Bridge Module for IIS" to better reflect its role as a generic bridging/compatibility layer and to avoid future confusion with any Microsoft offerings.
"HTTP Bridge Module" is a drop‑in replacement for the original Microsoft HttpPlatformHandler 1.2 with continued community maintenance. The existing configuration schema remain unchanged so existing deployments can adopt the new module without altering their configuration files.
The changes we make are released under the MIT license.
Find a release from the Releases section and you can see the installers (x86, x64, and ARM64).
Install them accordingly to the IIS/IIS Express builds you are using, and then you can apply your previous knowledge/configuration of HttpPlatformHandler with this new HTTP Bridge Module. Existing httpPlatform schema elements continue to work.
"HttpPlatformHandler v2" mimicked the original Microsoft product name and risked future confusion if Microsoft ships an updated official module. "HTTP Bridge Module for IIS" emphasizes its role as a community-maintained compatibility and bridging layer between IIS and arbitrary application servers while retaining full backward compatibility. For seamless upgrades we intentionally keep the original configuration schema names so existing web.config files do not require edits.
No. Continue to use the existing httpPlatform section and attributes. Only project documentation and branding changed.
