Detect a 301 redirect
Is there any easy way to detect that a page is being served because of a 301 redirect to it? We have reorganized some of our site so we have put 301 redirects in place for old URLs that people may use. But the powers that be do not want a completely silent redirect for users who may be using old bookmarks, published links, etc. They would like a message displayed asking them to update their sources. I thought a CGI variable might give me a hint, but I have not found the correct one if it exists. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:322192 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: Detect a 301 redirect
Well, a 301 redirect sort of means that the original file isn't there any more right. So that should be triggered via your 404 handler. You could intercept at that point and display message, along with the new location. andy -Original Message- From: Ian Skinner [mailto:h...@ilsweb.com] Sent: Tuesday, May 05, 2009 2:45 PM To: cf-talk Subject: Detect a 301 redirect Is there any easy way to detect that a page is being served because of a 301 redirect to it?

RE: Detect a 301 redirect
Ian: You could append a URL variable to the redirect URL that indicates the URL the redirect came from. In other words, something like: CFLOCATION URL=newUrl.cfm?oldUrl=oldUrl.cfm STATUSCODE=301 The new page would simply have to check for the oldUrl variable in the URL scope. -- Mosh Teitelbaum evoch, LLC http://www.evoch.com/ Ian Skinner wrote: Is there any easy way to detect that a page is being served because of a 301 redirect to it?

Re: Detect a 301 redirect
Perhaps your users could land on the original page, which displays a message telling them they are being redirected, then after 5 seconds (or whatever) the 301 redirect kicks in and moves them to the new page. This could easily be done with a cfheader/sleep/cflocation combo.

Re: Detect a 301 redirect
Do you know what one of these pages is? Maybe you could do a GetHttpRequestData() call and introspect the headers key of the return struct. Maybe something there will give you what you need.

I thought a CGI variable might give me a hint, but I have not found the correct one if it exists. The GetHttpRequestData is designed to get header information and the numeric code returned. There is an example of it working in the CFMX 7 livedocs site: http://livedocs.adobe.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=ColdFusion_Documentationfile=0482.htm If that does not meet your needs. The other way I know of getting that type of info would be through a Servlet. If you either feel adventurous or are pretty decent with Java you could code a custom tag in Java. If I remember correctly, the custom tag uses both the http request and response methods, between the two you should be able to get the custom tag to return whatever code you are looking for. --JW ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:322204 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Detect a 301 redirect
Can't remember, are you using IIS or Apache? I know that in Apache you can define an actual file for each specific server code. So you could have a 301.cfm which gets registered in the web server. That file gets triggered any time the server returns that error. I would assume that IIS has the same mechanism. Maybe that would work for you? andy -Original Message- From: Ian Skinner [mailto:h...@ilsweb.com] Sent: Tuesday, May 05, 2009 3:14 PM To: cf-talk Subject: Re: Detect a 301 redirect Andy Matthews wrote: Well, a 301 redirect sort of means that the original file isn't there any more right.
