6.15.4 Precautions related to error page customization

The precautions related to error page customization by the in-process HTTP server are as follows:

• When the HTTP response is an HTML file, if another file (such as an image file) is being referenced from that HTML, the error page might not be properly displayed.

• Note that depending on the browser settings, if the status code indicates an error and if the size of the response body is small, the response body MIGHT be replaced by a browser-specific message. Note that in the default error page displayed when an error page is not specifically customized, the size of the response body is small.

• If the value specified in the redirect URL matches with the value specified for the request URL and if the same error status occurs after redirection, note that the client keeps redirecting the requests.

• When redirect corresponding to the status code is implemented, the query string added to the request URL when an error occurs, is not added to the redirect URL. Also, when a session is managed by URL rewriting, the session cannot be inherited even if the request is redirected to the same Web application as the error page.
