Partial URI rewrite v 4.5

Hi,

If you always want to redirect requests that start with "/my/very/long", you could use something like this:

rule my_rule {
   if (http_uri starts_with "/my/very/long/") {
      redirect to "https://www.foorbar.com/our/very/log/%u"
   } else {
      use pool http_pool
   }
}

Else, if a string comparison won't work, you could use matches_regex to describe when to issue the redirect:

rule my_rule {
   if (http_uri matches_regex "/my/very/long/(?:some_dynamic_string)") {
      redirect to "https://www.foorbar.com/our/very/log/%u"
   } else {
      use pool http_pool
   }
}

[Edits: the %u is substituted for the original URI. And it's more resource intensive to use matches_regex versus one of the string comparisons like starts_with, contains or ends_with.]

Aaron,

 

Thanks a lot!

 

I thought %u contains the entire URI, will my redirect become

 

https://www.foorbar.com/our/very/long/my/very/long/teh_rest_of_the_dynamic_uri

 

In any event, I will try it out.

 

 

Boris.

In the F5 lexicon, %h refers to the host and %u refers to the URI, so the example should work for you, assuming you're able to match just the requests you want redirected.

 

 

Thanks,

I think Boris is right, that the URI will contain both the old part and the new part that way.

He'd need to use substr or some other text manipulation to re-build the URI, maybe something like this?

rule my_rule {
   if (tolower(http_uri) starts_with "/my/very/long/") {
      redirect to https://www.foorbar.com/our/very/long/ + substr(http_uri, 14)
   } else {
      use pool http_pool
   }
}
