Ie Friendly Error Messages

'14 Friendly HTTP Error Pages ★★★★★★★★★★★★★★★ EricLaw [ex-MSFT]August 18, 20100 Share 0 0 Internet Explorer 5 and later will show a “Friendly” HTTP Error page if the server returns certain HTTP Error status codes with show friendly http error messages chrome a short message body. The intent is to replace a terse server message like show friendly http error messages iis this one: …with a page which may be slightly more helpful to the average user, like this one: Unfortunately, IE's logic isn't smart 500 - internal server error. enough to detect that, say, the response was a tiny HTML page with a META Refresh pointed at a different page, meaning that the META Refresh won't work until you pad the HTML response with enough text to be deemed "non-terse." A common question from web developers is: What makes IE decide to show a friendly error page? The answer is that the server’s response must meet two criteria: The HTTP Status code must be [400, 403, 404, 405, 406, 408, 409, 410, 500, 501, 505] The HTTP Response body’s byte length must be shorter than a threshold value If the server’s response meets both criteria, then IE will show its own Friendly HTTP Error page instead of the server’s terse response. The byte length thresholds are stored in the registry in HKEY_LOCAL_MACHINE under the subkey \SOFTWARE\Microsoft\Internet Explorer\Main\ErrorThresholds. The default threshold is 256 bytes for the response codes [403, 405, 410] and 512 bytes for response codes [400, 404, 406, 408, 409, 500, 501, 505]. If the registry entry is missing for one of the status codes, its threshold defaults to 512 bytes. I wrote a simple script which allows you to test IE’s Friendly HTTP Error pages using Meddler. The next most common question is: How do I prevent IE from showing the friendly error page? If a user wants to prevent display of all Friendly HTTP Error pages, they can untick an option in the Internet Control Panel's Advanced tab, then restart IE. Of course, only the Friendly HTTP Error pages can be disabled in this way; other Friendly Error pages (like the DNS Lookup error or TCP/IP Connection failure page) cannot be disabled because IE has no other content from the server to display instead. Of course, it is impractical (and not necessarily desirable) to reconfigure IE on all client machines, so most servers that wish to ensure that users will see a given HTTP error message will pad the response with spaces or other characters until the response body leng

Microsoft notes in knowledge base article KB294807: HOW TO: Turn Off the Internet Explorer 5.x and 6.x "Show Friendly HTTP Error Messages" Feature on the Server Side ...these "friendly" error messages are only displayed if the response that is sent to the client is less than or equal to a specified threshold. For example, to see the exact text of an HTTP 500 response, the content length must be greater than 512 bytes. Implement this padding. To do this, use the VBScript String function to return a string of the same character, which is one more than the ErrorThreshold that Internet Explorer 5.x uses to display the friendly error message. For example, add the following line immediately before the tag of 500-100.asp: <% Response.Write String(513, "_") %> Make it bigger So i bulk up response page to:
