Hi everybody,

I need to remove the values of a response header. For example:

access-control-allow-headers    ----->  X-Request-UUID, X-Web-Optimize-Response, X-Web-Client-Id, X-Web-City-Id, X-Web-ClientI

I need to remove \"X-Web-City-Id\" and keep everything as they are.

I couldn`t find a related iRule. 

I would appreciate it if somebody could help me with this.

Best,

Ali

The F5 Certification is excited to announce that all five of the NEW F5 Certified BIG-IP Administrator Certification (F5 CAB) exams are now live and available to schedule via the new Education Services Portal.

Hello Asamadyar.

If the header is located in the Response, you could remove it with next iRule.

when HTTP_RESPONSE\n\tHTTP::header remove \"X-Web-City-Id\"\n}

Take into account that you would need a HTTP profile applied.

Many thanks, Dario_Garrido 

I don`t want to remove the header; I need to remove one value.

header ------------------------------------------- value

x-x-x                                                       t1, t2, t3, t4, t5

And I need to remove, for example, \"t3\" and keep everything intact in the response header.

I think your code will completely remove the header (x-x-x).

Hello Asamadyar.

Try with this code

when HTTP_RESPONSE {\n\tif { [HTTP::header \"access-control-allow-headers\"] ne \"\" } {\n\t\tif { [HTTP::header \"access-control-allow-headers\"] contains \",\" }{\n\t\t\tset acheaders [split [HTTP::header \"access-control-allow-headers\"] \",\"]\n\t\t\tset output \"\"\n\t\t\tforeach acheader $acheaders {\n\t\t\t\tif { $output eq \"\" } {\n\t\t\t\t\tif { !($acheader contains \"X-Web-City-Id\") } { set output \"$acheader\" }\n\t\t\t\t} else {\n\t\t\t\t\tif { !($acheader contains \"X-Web-City-Id\") } { set output \"$output,$acheader\" }\n\t\t\t\t}\n\t\t\t}\n\t\t\t#log local0. \"INPUT: [HTTP::header \"access-control-allow-headers\"]\"\n\t\t\tHTTP::header replace \"access-control-allow-headers\" $output\n\t\t\t#log local0. \"OUTPUT: [HTTP::header \"access-control-allow-headers\"]\"\n\t\t}\n\t}\n}
