Replacing in the URI ; http -> https and port 80 -> 443

Thanks

I need to be able to replace the http -> https and port 80 -> 443 which is in the URI .( See Example Below ) I also may need to replace the Language from say EN ( english) to FR (French) . I am looking for an elegant way to make relacements in the URI.

 

 

Thanks

 

 

 

Before:

 

 

https://testlab-d.tdx.dorion.com/amserver/UI/Login?goto=http%3A%2F%2Ftestlab-d.tdx.dorion.com%3A80%2Fperform%2FLogin.do%3FLANGUAGE%3DEN

 

 

After:

 

 

https://testlab-d.tdx.dorion.com/amserver/UI/Login?goto=https%3A%2F%2Ftestlab-d.tdx.dorion.com%3A443%2Fperform%2FLogin.do%3FLANGUAGE%3DEN

 

The built-in string map TCL command is probably what you'll want.

Here's an example:

when HTTP_REQUEST {
  set query [HTTP::query]
  set new_query [string map {goto=http% goto=https% %3A80% %3A443% %3DEN %3DFR} $query]
  HTTP::query $new_query
}

-or- in one line:

 when HTTP_REQUEST {
  HTTP::query [string map {goto=http% goto=https% %3A80% %3A443% %3DEN %3DFR} [HTTP::query]]
}

The first one is better for debugging...

Thanks Joe

Hi Joe;

 

 

Tried the following command and it does not appear to work. HTTP_REQUEST is

 

 

https://secureinternal-d.tmi.telus.com/amserver/UI/Login?goto=https%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A443%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

 

 

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] contains "goto"} {

 

HTTP::query [string map {goto=http% goto=https% %3A80% %3A443%} [HTTP::query]]

 

log local0. "http string map is [HTTP::query]"

 

}

 

}

 

 

ltm log output

 

 

Nov 22 08:30:35 tmm tmm[702]: Rule D3_INT1_SECURE_REDIRECT_NEW : http string map is goto=http%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A80%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

 

some of our variables are cached in the initial request so after making modifications of them (in your case with the HTTP::query command), if you try to access the value it will still return the original cached value. The value is changed, just not in the accessor variable. Have you verified that you servers are not receiving the correct value either by a log file or tcpdump?

Hi Joe;

 

 

Yes confirmed that downstream node (Sun Java Web Server) is receiving incorrect URL

The example worked for me:

when RULE_INIT {
 test the string map replacement
set aString ""
unset aString
log local0. " "
set aString "/amserver/UI/Login?goto=http%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A80%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN"
log local0. "original: $aString"
log local0. "new     : [string map {goto=http% goto=https% %3A80% %3A443%} $aString]"
}
when HTTP_REQUEST {
 test the actual replacement in the URI
if { [HTTP::uri] contains "goto"} {
HTTP::query [string map {goto=http% goto=https% %3A80% %3A443%} [HTTP::query]]
log local0. "this doesn't get updated:               [HTTP::query]"
log local0. "this is the actual value that gets set: [string map {goto=http% goto=https% %3A80% %3A443%} [HTTP::query]]"
}
}

Rule : original: /amserver/UI/Login?goto=http%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A80%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

Rule : new : /amserver/UI/Login?goto=https%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A443%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

Rule string_map_test_rule : this doesn't get updated: goto=http%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A80%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

Rule string_map_test_rule : this is the actual value that gets set: goto=https%3A%2F%2Fsecureinternal-d.tmi.telus.com%3A443%2Feperformance%2FLogin.do%3FLANGUAGE%3DEN

Are you sure you're using string map in the form:

set updated_string [string map {find_this replace_with_this} source_string]

Aaron;

 

 

My tests mirror yours however having trouble building the full URI. Do you have a recommendation here?

 

 

If you're setting the query to the updated value using HTTP::query and string map, you shouldn't need to modify the URI.

 

 

Can you provide more detail on what you're trying to do and what's not working?

 

 

Thanks,

 

Aaron
