NimbostratusHTTP redirect not working
I have the following I rule that is working however it will not redirect uppercase /LIVELINK/LIVELINK.EXE Any ideas on how to get it to redirect both upper and lower case?
when HTTP_REQUEST {
parse the uri
switch -glob [string tolower [HTTP::uri]] {
*/livelink/livelink.exe* {
replace each instance of /livelink/livelink.exe with /OTCS/cs.exe in the uri
set replaceURI [string map [list /livelink/livelink.exe /OTCS/cs.exe] [HTTP::uri]]
construct the redirect
set cachecontrol {no-cache}
set pragma {no-cache}
set location "http://ContentServerQA.idexxi.com$replaceURI"
HTTP::respond 301 noserver "Location" $location "Cache-Control" $cachecontrol "Pragma" $pragma "Connection" "close"
}
}

ChrisBlack_1713This post didn't come out as I had expected. Basically I am trying to redirect. FROM http://livelinkqa.idexxi.com/livelink/livelink.exe* http://livelinkqa.idexxi.com/LIVELINK/LIVELINK.EXE* To http://ContentServerQA.idexxi.com/otcs/cs.exe- susand_126519
Hi Chris, You shouldn't need the switch. This should do it:
when HTTP_REQUEST { if { [string tolower [HTTP::uri]] eq "/livelink/livelink.exe" } { HTTP::redirect "http://[HTTP::host]/otcs/cs.exe" } }See if the above works to make sure the uri is being matched then you can add the code to create a custom response if you still need to.
- ChrisBlack_1713Would this preserve the portion of the URL after /livelink/livelink.exe

In the above if, probably want starts_with instead of eq, as there where * in the orginal switch.
The switch should work though, not sure why it doesn't. Maybe remove the leading *, the URI should start with the / after the hostname.

when HTTP_REQUEST { if { [string tolower [HTTP::uri]] starts_with "/livelink/livelink.exe" } { HTTP::redirect "http://[HTTP::host]/otcs/cs.exe" } }
Would this preserve the portion of the URL after /livelink/livelink.exe?
shaggywhat could come after /livelink/livelink.exe? is it more URL or is it a query?- ChrisBlack_1713Yeah.... We have upgraded an application. So the hostname, virtual directory, and .exe are different however the rest of the URL is still accurate. EXAMPLE http://livelinkqa.idexxi.com/livelink/livelink.exe?func=ll&objId=598743&objAction=browse&viewType=1 RE DIRECT TO http://contentserverqa.idexxi.com/OTCS/cs.exe?func=ll&objId=598743&objAction=browse&viewType=1
- ChrisBlack_1713And the iRule I have is working just not for both cases. I have only been able to make it work for one or the other.

I resolved the issue by replacing [HTTP::uri]] in set replaceURI [string map [list /livelink/livelink.exe /OTCS/cs.exe] [HTTP::uri]]
With [string tolower [HTTP::uri]]]
Now it is redirecting both cases correctly. Thanks for your help!

OK, I see the problem, though I don't know the fix off the top of my head. Your switch matches on both cases, but your string map only matches the lower case version. Here is the output of what happens with each
Lowercase works: GET /livelink/livelink.exe/isthisstillhere HTTP/1.0
HTTP/1.0 301 Moved Permanently Location: http://ContentServerQA.idexxi.com/OTCS/cs.exe/isthisstillhere Cache-Control: no-cache Pragma: no-cache Connection: close Content-Length: 0Uppercase matches the switch, but not the string map. See the LIVELINK still in the URL
GET /LIVELINK/LIVELINK.exe/thisshouldstillbethere?andthis=this HTTP/1.0 HTTP/1.0 301 Moved Permanently Location: http://ContentServerQA.idexxi.com/LIVELINK/LIVELINK.exe/thisshouldstillbethere?andthis=this Cache-Control: no-cache Pragma: no-cache Connection: close Content-Length: 0maybe set HTTP::uri to a variable, string tolower that assignment. Then switch and string map on the now lowercase variable??
- mimlo_61970
Yep, that worked. Try this:
when HTTP_REQUEST { set myuri [string tolower [HTTP::uri]] switch -glob $myuri { */livelink/livelink.exe* { set replaceURI [string map [list /livelink/livelink.exe /OTCS/cs.exe] $myuri ] set cachecontrol {no-cache} set pragma {no-cache} set location "http://ContentServerQA.idexxi.com$replaceURI" HTTP::respond 301 noserver "Location" $location "Cache-Control" $cachecontrol "Pragma" $pragma "Connection" "close" } } }- ChrisBlack_1713THANKS!!
