I think I just figured it out guys Mohamed_Ahmed_Kansoh CA_Valli
Paste this and run it. It worked out for me. Now any of you can explain why this works?? Is this a bug with F5? At least it seems to me. If it is, how can I let them know so they can fix it.
when HTTP_REQUEST { if { [HTTP::uri] eq "/demo2" } { HTTP::header insert "{esbsoapheader}userName" "spencer" foreach aHeader [HTTP::header names] { log local0. "HTTP Request Headers: $aHeader: [HTTP::header value $aHeader]" } log local0. "***************REMOVING BAD HEADER************" HTTP::header remove "\\{esbsoapheader\\}userName" foreach aHeader [HTTP::header names] { log local0. "HTTP Request Headers: $aHeader: [HTTP::header value $aHeader]" } } }

AdminNice work, Spencer_Aranda! The reason you need this is to escape the special characters. Both "\" and "{ }" are special characters in Tcl, so the "\\{" pattern is to escape both so you can actual match as the string as intended.
