What I am trying to do is have / and specific data group list URIs going to pool B and the rest of the traffic going to pool A. Issue is that when a URI contains part of an entry in the data group list it uses that pool (example /test is in the dgl and if /test/documents is requested it goes to the dgl not pool A). So I tried the following irule but it is not working. when HTTP_REQUEST { if { ( [HTTP::uri] equals "/A/documents" ) or ( [HTTP::uri] equals "/B/documents" ) or ( [HTTP::uri] equals "/A/document-library" ) or ( [HTTP::uri] equals "/B/document-library" ) or ( [HTTP::uri] equals "/A/video" )} { pool pool_default.domain.com } if { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] starts_with dgl_aem.domain.com] ) } { pool pool_alternate.domain.com } else { pool pool_default.domain.com } }

Isn't it working as expected? class match[string tolower[HTTP::uri]]starts_with dgl_aem.domain.com] which is class match "/test/documents" starts_with "/test" Should use "equals" instead, for your logic to work ?

What I am looking for is an irule that can route: if /A/docs, /B/docs, or /C/docs use pool1. Then, if not those URIs but is / or contained in the data group list (dgl_aem.domain.com) use pool2. else use pool1. So, if the URI /A/testsite is used and /A is definded in the data group list it will use the pool2, but if /A/docs is used it will goto pool1. Right now with my iRule /A/testsite and /A/docs all goto pool2

Try with [class match [string tolower [HTTP::uri]] contains dgl_aem.domain.com]

class match[string tolower[HTTP::uri]]starts_with dgl_aem.domain.com]

which is

class match "/test/documents" starts_with "/test"

Should use "equals" instead, for your logic to work ?

  If I enter http://www.domain.com/A/docs/legal-notices I still goto pool_default_domain.com vs. pool_alternate.com. I need if the top IF statements match to exit the irule and use the defined pool. It seems like the irule is reading the last success not the first.

My irule did not dsiplay very well - reposting so it is easier to read. when HTTP_REQUEST { if { ( [HTTP::uri] equals "/A/documents" ) or ( [HTTP::uri] equals "/B/documents" ) or ( [HTTP::uri] equals "/C/documents" ) or ( [HTTP::uri] equals "/D/documents" ) or ( [HTTP::uri] equals "/E/documents" )} { pool pool_default_domain.com } if { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] starts_with dgl_aem.domain.com] ) } { pool pool_alternate.com } else { pool pool_default.domain.com }

Are your referring to this:

if { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] starts_with dgl_aem.domain.com] ) } {

What is the string list in dgl_aem.domain.com expected to match here?

  Originally I had the following irule: when HTTP_REQUEST { if { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] starts_with dgl_aem.domain.com] ) } { pool pool_alternate.com } else { pool pool_default.domain.com } The data group list (dgl_aem.domain.com) had all the URIs for the alternate pool. The problem that has come up is that for example /legal-documents/ is defined in the data group list to (as it should) to point to the alternate pool but the URI /legal-documents/insurance needs to point to the default pool. So to allow these few exception URIs to hit the default pool before the data group was read I thought I could do this iRule: when HTTP_REQUEST { if { ( [HTTP::uri] equals "/A/documents" ) or ( [HTTP::uri] equals "/B/documents" ) or ( [HTTP::uri] equals "/C/documents" ) or ( [HTTP::uri] equals "/D/documents" ) or ( [HTTP::uri] equals "/E/documents" )} { pool pool_default_domain.com } if { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] starts_with dgl_aem.domain.com] ) } { pool pool_alternate.com } else { pool pool_default.domain.com }

I think "starts_with" is the one which is failing here. You can have the original logic but change "starts_with" to "contains". But your dgl shouldn't have the end forward slash. Or if really wants the first if clause to remain, do a "return" so that next following if clause doesn't execute.

  I did change the starts_with to contains but also had to do a re-write from if/if to elseif statements to trigger script exits upon successful match. This iRule is working. Thank you for your responses. when HTTP_REQUEST { if { ( [HTTP::uri] contains "/legal/documents" ) } { pool pool_host.domain.com_80 } elseif { ( [HTTP::uri] contains "/legal-notices/documents" ) } { pool pool_host.domain.com_80 } elseif { ( [HTTP::uri] contains "/legal-families/document-library" ) } { pool pool_host.domain.com_80 } elseif { ( [HTTP::uri] contains "/legal-producer/document-library" ) } { pool pool_host.domain.com_80 } elseif { ( [HTTP::uri] contains "/producer/document-library" ) } { pool pool_host.domain.com_80 } elseif { ( [HTTP::uri] equals "/" ) or ( [class match [string tolower [HTTP::uri]] contains dgl_host.domain.com_80] ) } { pool pool_ALThost.domain.com_80 } else { pool pool_host.domain.com_80 } }
