Need HTTP Redirect assistance

Hi there,

 

 

Do you want to redirect the client (so the browser address bar shows the update) or do you want to rewrite the URI and send the request to the pool?

 

 

I'm not sure under what circumstances you want to rewrite or redirect to /member?cid=uri, but here are two methods:

 

 

Redirect

 

HTTP::redirect "http://[HTTP::host]/member?cid=[HTTP::uri]

 

 

Rewrite URI

 

HTTP::uri "/member?cid=[HTTP::uri]"

 

 

Also, I think you'd want to replace HTTP::path with HTTP::uri for this line in your sample above:

 

/bp { HTTP::path "/member?cid=bp" }

 

 

HTTP::path does not include the query string. So I would think you'd run into a problem using HTTP::path to set a path that includes a query string if the original request already had a query string.

 

 

Original URI: /test/file.ext?param1=param2

 

Command: HTTP::path /member?cid=bp

 

Resulting URI?? /member?cid=bp?param1=param2

Thanks a lot for the input! I believe you have gotten me very close, however; it's not quite right. The uri rewrite is not changing, however when I replace HTTP::uri with bp it works fine. Here's what I have:

 

 

when HTTP_REQUEST {

 

switch [HTTP::path] {

 

/ { HTTP::path "/member" }

 

/tooljournals { HTTP::path "/tooljournals" }

 

/HTTP::uri { HTTP::uri "/member?cid=[HTTP::uri]" }

 

/eb-member-earAdmin { HTTP::respond 404 content "RESOURCE NOT FOUND" }

 

/admin { HTTP::respond 404 content "RESOURCE NOT FOUND" }

 

/adminTool { HTTP::respond 404 content "RESOURCE NOT FOUND" }

 

}

 

}

 

 

Appreciate your help.

What are the symptoms of the problem you're seeing with the last rule? Which requests are not being rewritten correctly? What are they being rewritten to?

I think this might be what you're looking for:

  
  when HTTP_REQUEST {  
    
     log local0. "[IP::client_addr]:[TCP::client_port]: New request to : [HTTP::uri]"  
     switch [HTTP::path] {  
        "/" { HTTP::path "/member" }  
        "/bp" { HTTP::uri "/member?cid=[HTTP::uri]" }  
        "/eb-member-earAdmin" -  
        "/admin" -  
        "/adminTool" {  
           HTTP::respond 404 content "\  
              RESOURCE NOT FOUND"  
        }  
     }  
  }  
  when HTTP_REQUEST priority 501 {  
      Log a debug statement in a rule event with a different priority so the HTTP::uri value isn't cached.  
      This event can be removed after testing.  
     log local0. "[IP::client_addr]:[TCP::client_port]: Modified URI: [HTTP::uri]" 
  }  
  

What were you trying to do with the case below? It's rewriting the path to the same as it was when requested:

"/tooljournals" { HTTP::path "/tooljournals" }

Also, if you want to use the same action for multiple cases, you can add them with hyphens as shown above for /eb-member-earAdmin, /admin and /adminTool.

Thanks a lot for your input, Aaron. The only thing is that the "/bp" can be anything. Whatever that

 

value is, I need to rewrite it in the uri.

 

 

"/bp" { HTTP::uri "/member?cid=[HTTP::uri]" }

 

 

With "/toolsjournals" I need any uri that starts with this, to rewrite the uri as is.

 

My thinking was that if I didn't do this, then the condition above would catch it, and the uri

 

would rewrite like this. "/member?cid=tooljournals"

 

 

"/tooljournals" { HTTP::path "/tooljournals" }

 

 

This make more sense?

 

 

starts_with "/tooljournals" { HTTP::uri "[HTTP::uri]" }

 

 

Thanks so much!

How about this then?

  
    when HTTP_REQUEST {    
        
       log local0. "[IP::client_addr]:[TCP::client_port]: New request to : [HTTP::uri]"    
    
       switch -glob [HTTP::path] {    
          "/" { HTTP::path "/member" }   
          "/tooljournals*" {  do nothing }  
          "/eb-member-earAdmin" -    
          "/admin" -    
          "/adminTool" {    
             HTTP::respond 404 content "\    
                RESOURCE NOT FOUND"    
          }  
          default {  
             HTTP::uri "/member?cid=[HTTP::uri]"   
          }  
       }    
    }    
    when HTTP_REQUEST priority 501 {    
        Log a debug statement in a rule event with a different priority so the HTTP::uri value isn't cached.    
        This event can be removed after testing.    
       log local0. "[IP::client_addr]:[TCP::client_port]: Modified URI: [HTTP::uri]"   
    }  
  

Aaron

Ah, I think you'd need to not rewrite if the path already starts with /member/. Can you try this:

 
 when HTTP_REQUEST { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: New request to : [HTTP::uri]"     
      
    switch -glob [HTTP::path] { 
       "/" { HTTP::path "/member" } 
       "/member/*" - 
       "/tooljournals*" {  do nothing } 
       "/eb-member-earAdmin" -     
       "/admin" -     
       "/adminTool" { 
          HTTP::respond 404 content "\     
             RESOURCE NOT FOUND"     
       } 
       default { 
          HTTP::uri "/member/?cid=[HTTP::uri]"    
       } 
    } 
 } 
 when HTTP_REQUEST priority 501 { 
     Log a debug statement in a rule event with a different priority so the HTTP::uri value isn't cached.     
     This event can be removed after testing.     
    log local0. "[IP::client_addr]:[TCP::client_port]: Modified URI: [HTTP::uri]"    
 } 
 

Aaron

Thanks for all the help. It's working almost perfectly now. Only issue that I'm working on now is an unexpected "/" after the rewrite.

 

 

So we are seeing:

 

 

https://abcwww.mynurseonline.com/member/?cid=/bc

 

 

We'd need to see:

 

 

https://abcwww.mynurseonline.com/member/?cid=bc

 

 

Thanks,

The URI will always start with a leading forward slash. If you need to remove this when using the URI in the redirect, you can use 'string trimleft' (Click here😞

 
  when HTTP_REQUEST {  
    
     log local0. "[IP::client_addr]:[TCP::client_port]: New request to : [HTTP::uri]"      
        
     switch -glob [HTTP::path] {  
        "/" { HTTP::path "/member" }  
        "/member/*" -  
        "/tooljournals*" {  do nothing }  
        "/eb-member-earAdmin" -      
        "/admin" -      
        "/adminTool" {  
           HTTP::respond 404 content "\      
              RESOURCE NOT FOUND"      
        }  
        default {  
           HTTP::uri "/member/?cid=[string trimleft [HTTP::uri] /]" 
        }  
     }  
  }  
  when HTTP_REQUEST priority 501 {  
      Log a debug statement in a rule event with a different priority so the HTTP::uri value isn't cached.      
      This event can be removed after testing.      
     log local0. "[IP::client_addr]:[TCP::client_port]: Modified URI: [HTTP::uri]"     
  }

Looks like it is dropping everything after the first slash. In other works it looks like this.

 

 

https://abcwww.mynurseonline.com/bp

 

 

Thanks again.

string trimleft should work:

 

 

% set uri /test/1/2/3/

 

/test/1/2/3/

 

 

% puts "/member/?cid=[string trimleft $uri /]"

 

/member/?cid=test/1/2/3/

 

 

Can you post a sample or two of the logs from it not working?

 

 

Thanks,

 

Aaron
