Rewrite URL and change pool trouble

Did you try my rule? I verified that the one I posted works. Your's has several syntax errors.

yes, I copied yours exactly and got that error message when I tried to save. When I removed the elseif statement, it will allow me to save. I probably have an extra space or something and will try to figure it out.

 

 

Also, does this make sense?

 

 

I am just trying to replace /blog with /blogs/menopauseinsightblog

 

 

I though the string had to be the length of the uri replacement string. Also, there will be other pararmeters after the string that I don't want replaced.

 

 

i.e. /blog?name=star would turn into /blogs/menopauseinsightblog?name=star

 

 

 

That's odd. I just cut+pasted from the post on v9.2.2 and it loaded fine. I'd try to remove all trailing spaces from your lines and see if that fixes it. As for the substitution, here's a go at it.

when HTTP_REQUEST {
  if { ([HTTP::uri] starts_with "/blog") and 
      !([HTTP::uri] starts_with "/blogs/menapauseinsightblog") } {
      HTTP::uri "/blogs/menapauseinsightblog[string range [HTTP::uri] 5 end]"
  }
}

This will replace all uris that start with "/blog" but don't start with "/blogs/menapauseinsightblog" with the new uri appended with character 6 to the end of the original uri.

Keep in mind that this will blanketly replace the strings as such

/blog?user=foo => /blogs/menapauseinsightblog?user=foo

/blogs?user=foo => /blogs/menapauseinsightblogs?user=foo

/bloggin?user=foo => /blogs/menapauseinsightblogsgin?user=foo

Just keep that in mind...

I am currently using 9.05 on the BigIP. Would that impact some of the iRule commands?

 

 

BTW Thanks for the help!

I think I am getting very close....

 

 

Here is the iRule so far:

 

 

when HTTP_REQUEST {

 

if { ([HTTP::uri] starts_with "/blog") and

 

!([HTTP::uri] starts_with "/blogs/menopauseinsight") } {

 

HTTP::uri "/blogs/menopauseinsight[string range [HTTP::uri] 5 end]"

 

}

 

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

 

HTTP::header replace "Host" "cs.geosign.com"

 

}

 

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

 

HTTP::header replace "Host" "cs.geosign.com"

 

}

 

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

 

pool MIS-WEB21-CS

 

} else {

 

pool MIS-WEB20-4

 

}

 

}

 

 

The only problem that I have now is that the blog server cs.geosign.com uses style sheets. The other requests get requests that I need to have redirected are:

 

/Themes/Blogs/marvin3/style/print.css

 

/Utility/global.js?Version=2.0.60217.2664

 

/utility/EULA.GIF

 

 

These extra get requests don't seem to get caught by my uri contains rules? Therefore, they go to the wrong server.

contains is case sensitive. You'll need to use the "string tolower" command to make your string lower case and then compare against lower case strings

Give this a shot:

when HTTP_REQUEST {
  set uri [string tolower [HTTP::uri]]
  if { ($uri starts_with "/blog") and
       !($uri starts_with "/blogs/menopauseinsight") } {
       HTTP::uri "/blogs/menopauseinsight[string range [HTTP::uri] 5 end]"
  }
  if { $uri contains "blog" } { 
   HTTP::header replace "Host" "cs.geosign.com"
  } 
  if { $uri contains "utility" } { 
   HTTP::header replace "Host" "cs.geosign.com"
  }
  if { $uri contains "blog" } {
    pool MIS-WEB21-CS 
 } else { 
   pool MIS-WEB20-4 
 }
}
