I have a servicestack server that uses a response filter to add data validation messages to our service. My Put/Post handlers return a HttpResult object with Response set to our validation object. The response filter then decomposes this object into a raw html string that it sets the Response object to. In order to get this to work I had to create a String.md file in “views” along with a blank html template file. The problem I am now seeing is when our custom html response contains a comma “,” the jsv fromater tries to serialize the string and throws an exception:

My question is how can i turn jsv off for these responses? Or is there a better way to return raw html? I cannot have my request handlers return a string since I need to control the response code and headers returned.
You can return a HTML string inside a HttpResult, e.g:

Is it possible to serve HTML pages with ServiceStack?
In addition to Markdown, we’ve added new MVC Razor Support you can see examples of at in:
