When goiing to https://www.foo.com/abc
The webserver is redirecting for authenticating to https://www.foo.com/login.jsp?targetURL=http://www.foo.com/abc
Is it possible to rewrite the URL (via iRules) so the target URL is https://www.foo.com/abc instead of http://www.foo.com/abc
Now it happens on an apache with 'proxypassreverse'
Any suggestion?

NimbostratusYes you should be able to do this with the following untested iRule
when HTTP_RESPONSE {
set $find "http://www.foo.com/abc"
set $replace "https://www.foo.com/abc"
if {[HTTP::is_redirect] and [HTTP::header value Location] contains "?targetURL=http://www.foo.com/abc"} {
HTTP::header replace Location [string map -nocase [-list $find $replace ] [HTTP::header value Location]]
}
}
I hope this helps

Any idea
Nimbostratus
when HTTP_RESPONSE {
set find "http://www.foo.com/abc"
set replace "https://www.foo.com/abc"
if {[HTTP::is_redirect] and [HTTP::header value Location] contains "?targetURL=http://www.foo.com/abc"} {
HTTP::header replace Location [string map -nocase [-list $find $replace ] [HTTP::header value Location]]
}
}
The variables for find and replace were not set right. The code above should be what you need.
Admin[string map -nocase [list $find $replace] [HTTP::header value Location]
Also note that the "$" should not be present on the two set commands. In TCL shell:
% set find "http://www.foo.com/abc"
http://www.foo.com/abc
% set replace "https://www.foo.com/abc"
https://www.foo.com/abc
% set location "Location: http://www.foo.com/abc/home.html"
Location: http://www.foo.com/abc/home.html
% string map [list $find $replace] $location
Location: https://www.foo.com/abc/home.html
Note that setting the variables not only takes up unnecessary cpu/memory, but it also requires the list command in the string map, which takes extra cpu cyles. Would be better just to define them unless there are multiple potential matches. This would be shortened to:
when HTTP_RESPONSE {
if {[HTTP::is_redirect] and [HTTP::header value Location] contains "?targetURL=http://www.foo.com/abc"} {
HTTP::header replace Location [string map -nocase {"http://www.foo.com/abc" "https://www.foo.com/abc"} [HTTP::header value Location]]
}
}
