Cirrusreplace part of URI for specific URL and pass remaining
Dear Community, I need to replace only specific part of URI i.e "/abc/defg/" with "/uvw/xyz/" in a URL. All other URLs should not be altered. "/abc/defg/" will appear in the begning of URI For e...
iRule It should be the following and any other additions can be added in a similar manner. You might consider speaking with the application team and have them perform the corrections on the server as this should only be done as a last resort in an iRule.
when CLIENT_ACCEPTED priority 500 { set DEFAULT_POOL [LB::server pool] } when HTTP_REQUEST priority 500 { if {[string tolower [HTTP::uri]] starts_with "/abc/defg/"} { HTTP::uri [string map {"/abc/defg/" "/uvw/xyz/"}[HTTP::uri]] pool pool_web } elseif {[string tolower [HTTP::uri]] starts_with "/123/456/"} { HTTP::uri [string map {"/123/456/" "/78/910/"}[HTTP::uri]] pool pool_web } elseif{[string tolower [HTTP::uri]] starts_with "/asdf-asdf/"} { HTTP::uri [string map {"/asdf-asdf/" "/lkjh-lkjh/"}[HTTP::uri]] pool pool_web } else { pool ${DEFAULT_POOL} } }

MVPiRule I have made some slight modifications to the iRule but I don't think it will resolve your issue but are best practices.
when HTTP_REQUEST priority 500 {
if {[string tolower [HTTP::uri]] starts_with "/abc/defg/"} {
HTTP::uri [string map {"/abc/defg/" "/uvw/xyz/"}[HTTP::uri]]
pool pool_web
}
}If you can provide additional detail as to what exactly isn't working for the additional URLs we might be able to assist further.

CirrusPaulius All other URLs that are not starting with "/abc/defg/" are stopped and I am getting connection reset error. Kindly provide an updated iRule.

iRule Do you have pool configured for the VS that your iRule is configured under? It would be helpful to see the configuration of your VS in order to properly configure an iRule to perform the task that you are expecting.

iRule The irule above should work but the following can be used to see if that fixes your issue in conjunction with a /32 OneConnect profile associated to the VS.
