Masking URL

I think the problem might be related to the cookies the system uses. For example, here is a request to the regular URL that works fine:

 

 

GET /?handler=/system/login/ok&login=craig.freyman@medpt.com&password=&next=/freyman/ HTTP/1.1

The second GET made by the client in the first example refers to a cookie and in the second example it does not. Could this be the reason I have to login twice?

The second query is missing the cookie, any reason why? What is different about the second query (concerning the BigIP)?

The only thing different about the second query is I am applying that IRULE to it that replaces the HOST. The first query goes to conference2.telept.com the second goes to performance.telept.com which is supposed to be bounced over to conference2.telept.com.

 

 

Is there some rule that will retain the cookie info when the HTTP Host header is changed?

I think your problem might be that the Location header contains the un-changed host name, yet the BREEZESESSION cookie is under the other domain. There are a couple of things you could do to test this out. One would be to update cookie to use a broader domain. Another approach would be to make sure the Location header points to the right host.

 

I'm trying to do determine if there is a cookie, if there is, to change the location. This doesnt work though:

 

 

when HTTP_REQUEST {

 

set foundcookie 0

 

HTTP::header replace Host conference2.telept.com

 

if {([HTTP::cookie exists])} {

 

set foundcookie 1

 

}

 

}

 

 

when HTTP_RESPONSE {

 

if {$foundcookie == 1} {

 

HTTP::header replace Location http://performance.telept.com/freyman/

 

}

 

}

 

 

I receive

 

 

01070151:3: Rule [mask-URL] error:

 

line 4: [wrong args] [HTTP::cookie exists]

You are missing the cookie name in the HTTP::cookie exists command.

HTTP::cookie exists - Returns a true value if the cookie exists.

when HTTP_REQUEST {
   set foundcookie 0
   HTTP::header replace Host conference2.telept.com
   if { [HTTP::cookie exists "enter_name_of_cookie_here"] } {
      set foundcookie 1
   }
}
when HTTP_RESPONSE {
   if {$foundcookie == 1} {
   HTTP::header replace Location http://performance.telept.com/freyman/
   }
}

You'd be better off looking for a 302 response status code and replacing the Location header then. The location header is only used on redirects and is not directly related to the cookie.

 

 

The other option would be to check if the cookie exists in the response and update it to have a domain of performance.telept.com.

 

 

You should try updating the location header first though.

Still not working right, whent he redirect happens one of the cookies gets lost. Is there a way to use the "cookie persistence profile?"

 

 

I don't think adding cookie persistence is going to help you as that adds another cookie used to persist to a backend server.

 

 

Perhaps you should try always updating the cookie in the response to have a broader domain. Also, you could check on the client to see where the cookie (under what domain) the cookie was saved.

 

Like this?

 

 

when HTTP_REQUEST {

 

HTTP::header replace Host conference2.telept.com

 

if {[HTTP::cookie exists BreezeLoginCookie]} {

 

HTTP::cookie domain .telept.com

 

}

 

}
