Pessoal, é o seguinte , instaleii o plugin do google para otimização de websites e ele me retornou o seguinte resultado:

[i]Ativar compactação

A compactação de recursos com gzip ou deflate pode reduzir o número de bytes enviados através da rede.

Sugestões para esta página

Compactar os seguintes recursos com o gzip pode reduzir seus tamanhos de transferência em 389.1KiB (72% de redução).
Compactar http://localhost:8080/.../jquery-ui.min.js pode economizar 150.0KiB (74% de redução).
Compactar http://www.superfish.com/ws/sf_code.jsp?.… pode economizar 109.7KiB (74% de redução).[/i]

Dei uma lida sobre o assunto, adicionei uns negocios no server.xml pra ativar compactação gzip mas não consegui, o que eu devo fazer para resolver este problema? algum software para “gzipar” o script? achei o http://www.refresh-sf.com/yui/ que faz isso, mas quando eu importo na página da erro tipo

Então se alguem já fez, por favor se puder me ajudar seria ótimo =)

Obs: estou utilizando o tomcat.

No Tomcat, você faz compression=“on” no server.xml…

Ai eu importo na página o .gz mesmo ? tipo

Porque eu adicionei aqui e ele retorna o erro no console:

Uncaught SyntaxError: Unexpected token ILLEGAL :8080/LaPizza/Scripts/SalvarFornecedor.js.gz:1

Segue meu Server.xml
