modifying HTTP::uri not working?

Hi Tom,

 

Have you tried removing the " " on your string trim?

Ok, I just tried that:

  
  when HTTP_REQUEST {  
      if { $::DEBUG }{  
           log "requri -> [HTTP::uri]"  
      }  
      HTTP::uri [string trimright [HTTP::uri] .html ]  
      if { $::DEBUG }{  
          log "newuri -> [HTTP::uri]"  
  

  
  Dec 28 13:24:14 local/tmm info tmm[2790]: 01220002:6: Rule myrule : requri -> '/blah.html'  
  Dec 28 13:24:14 local/tmm info tmm[2790]: 01220002:6: Rule myrule : newuri -> '/blah.html'  
  

So the .html still isn't being trimmed.

Most of the HTTP:: command values are cached in the same event of the same priority. See this post for details and a few options:

 

 

Manipulate a HTTP:path then continue to parse iRule

So I changed my code to read:

 

 

 
 when HTTP_REQUEST { 
     set myuri [HTTP::uri] 
     if { $::DEBUG }{ 
          log "requri -> $myuri" 
     } 
     set myuri [string trimright $myuri .html ] 
     if { $::DEBUG }{ 
         log "newuri -> $myuri" 
     } 
 

 

 

Now the trimming seems to be having as expected. Thanks.

You haven't actually set the URI to the new value though. If you just want to log the update, you could use this:

 
 when RULE_INIT { 
    set ::DEBUG 1 
 } 
 when HTTP_REQUEST { 
      if { $::DEBUG }{  
           log local0. "Original URI: [HTTP::uri] 
      }  
      HTTP::uri [string trimright [HTTP::uri] .html] 
 } 
 when HTTP_REQUEST priority 501 { 
  
     This event runs after the prior HTTP_REQUEST event at the default priority of 500 
     Remove or comment out this event once done testing 
    if { $::DEBUG }{  
       log local0. "Updated URI: [HTTP::uri] 
    }  
 }

Actually, string trimright won't work as you're expecting. It's not doing a replacement of .html--it's looking for any instance of any character in .html and removing it from the URI:

 

 

% string trimright /testtttt.html .html

 

/tes

 

 

If you want to remove .html from the URI, you could use string map:

 

 

% string map {.html ""} /testtttt.html

 

/testtttt

 

 

or for your iRule:

 

HTTP::path [string map {.html ""} [HTTP::path]]

 

 

Note that HTTP::path is the URI minus the query string. Assuming you only want to replace .html with nothing in the path this would be more precise.

Ok, I changed it to be:

 
 when HTTP_REQUEST { 
     set mypath [HTTP::path] 
     if { $::DEBUG }{ 
          log "reqpath -> $mypath" 
     } 
     set mypath [string map {.html ""} $mypath]  
     if { $::DEBUG }{ 
         log "newpath -> $mypath" 
     } 
     if { ! ($mypath ends_with "/") }{ 
         set mypath $mypath/ 
         if { $::DEBUG }{ 
             log "apppath -> $mypath" 
         } 
     } 
     HTTP::path $mypath 
     pool A 
 }
