'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 a short message http 500 internal server error internet explorer how to fix body.

page which may be slightly more helpful to the average user, like this one: Unfortunately, IE's logic isn't smart enough to detect that, say, show friendly http error messages iis 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 iis 500 error 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 length exceeds 512 bytes. For instance, Fiddler’s FailSession method contains the following code: if (iStatusCode >= 400) { if (strErr

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 errcommon Internet Explorer Error messages are:.. 52 Runtime Error This is a "bad file name or number" error in JavaScript. It means that the script cannot find a file it is looking for (web-page, course component) and is most likely a connectivity problem. Try to clear your temporary internet files which should resolve any further problems... If this does not then speak with the website administrator as there may be a problem with the websites server. 400 Bad File Request Usually means the syntax used in the url is incorrect (e.g. uppercase letter should be lowercase letter; wrong punctuation marks) 401 Unauthorised The website server is looking for some encryption key(s) from the client (your computer) and is not getting it. Also, a wrong password may have been entered. Try it again, paying close attention to case sensitivity.. 403 Forbidden/Access Denied Similar to 401, special permission is needed to access the website A password and/or username may not be correctly registered on the websites database. Other times the website server may not have the proper permissions set up on its directories... 404 File Not Found Server cannot find the file you requested. Refreshing the page (F5) should resolve this problem, although continued error messages may mean the page is no longer available, that there is considerable internet congestion (in which case the user should try again later). Alternatively the file could have been either been moved or deleted, or you entered the wrong URL or document name. Look at the URL. If a word looks misspelled, correct it and try it again. If that doesn't work backtrack by deleting information between each backslash, until you come to a page on that site that isn't a 404. From there you may be able to find the page you're looking for. This has to be the most common Internet Explorer Error message on the Internet! 408 Request Timeout Client (your computer) stopped the request before the server finished retrieving it. A user will either hit the stop button, close the browser, or click on a link before the page loads. Usually occurs when servers are slow or file sizes are large. 500 Internal Error Couldn't retrieve the HTML document because of server-configuration problems. Contact website administrator... 501 Not Implemented Web server doesn't support a requested feature. 502 Service Temporarily Overloaded Server congestion; too many connections; high traffic. Keep trying until the page loads. This can be a common occurrence at peak news times eg. the Twin Towers during September 2001 brought CNN and the BBC news sites to a sl
