Hey Nick, thank you for your response. Yeah, I found a document describing the changes you guys made .. if I am not mistaking it stated that HTTP Status Codes in the 200 and 300 series are now excluded from the ErrorOverride; thus only override 40x and 50x status codes now. Unfortunately defaulting to the proxy's error pages in this case and trying to override the 401 is somewhat difficult since this is an "authorization required" status code coming from an IIS server with Integrated Windows Authentication. Is there any other way I could potentionally trap 404 errors from the back-end server and perform some sort of action on it? I don't think it's possible with mod_rewrite, but would this be possible with mod_filter? If not, would you know where - in the source code - they excluded the 20x and 30x statuscodes from ProxyErrorOverride?. I've been looking thru the code but have not yet been able to find it. :( Richard ----- Original Message ---- From: Nick Kew <nick@xxxxxxxxxxxx> To: users@xxxxxxxxxxxxxxxx Sent: Tuesday, August 19, 2008 7:34:47 PM Subject: Re: Apache 2.2.8 + ProxyErrorOverride errors Richard de Vries wrote: > (all on one line, so chopped) We recently made some fixes to ProxyErrorOverride, but I don't recollect the details. Googling the dev list would no doubt find it. In the absence of a better solution, you could perhaps default to serving the proxy's error pages, but override that for selected statuses by configuring ErrorDocuments for them. -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
