When you say you have a "authentication handler", do you mean that it is triggered by PythonAuthenHandler directive. If it is and you are returning HTML from it and it represents the complete response for the request, you must return apache.DONE and not apache.OK. If you do not return apache.DONE, the content handler will still be executed and thus any HTML that the content handler itself generates will be appended to the result. The only other time you would likely see HTML from two places being concatenated together, is when you are generating HTML but then returning an error status such as apache.HTTP_UNAUTHORIZED. In other words, you were wanting to generate a custom error response page. If you simply return apache.HTTP_UNAUTHORIZED in that situation, then Apache will still go on to generate an error document page which gets appended to your output. In that situation you should instead use: req.status = apache.HTTP_UNAUTHORIZED # generate HTML return apache.OK If this is a handler other than PythonHandler, again, you should be returning apache.DONE and not apache.OK. I would suggest that you post what your Apache configuration directives are so it is clear what handlers are being executed and in what phases. Show a cut done version of what your handlers are doing would also be helpful. Graham > The HTML generated is a form, and the user information is used to > populate the default values.
