Guys, We have a Squid-2.5-STABLE14 + NTLM Authentication. I've been noticed that we have problems downloading some .msi files from internet. Downloads: 1. In some cases, as download .msi files, pop-up window from IE or Firefox appears, but never starts, hangs on 0%. 2. There are other cases downloading .msi files that starts, but it never completes 100%. It happens only with .msi files!!! From Microsoft's, Pyhton, FoxitReader sites and others. Really strange. Any ideas? ---------------------------------------------------------------- squid.conf # Porta que o Squid irá "escutar" http_port 3128 # Usuário e grupo do squid cache_effective_user proxy cache_effective_group proxy #redirect_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf # Tamanho do cache cache_mem 1000 MB cache_swap_low 90 cache_swap_high 95 memory_replacement_policy heap GDSF cache_replacement_policy heap LFUDA maximum_object_size 16 MB maximum_object_size_in_memory 40 KB cache_dir diskd /squidcache/cache/1 10000 64 256 Q1=64 Q2=72 cache_dir diskd /squidcache/cache/2 10000 64 256 Q1=64 Q2=72 cache_dir diskd /squidcache/cache/3 10000 64 256 Q1=64 Q2=72 cache_dir diskd /squidcache/cache/4 10000 64 256 Q1=64 Q2=72 cache_dir diskd /squidcache/cache/5 10000 64 256 Q1=64 Q2=72 cache_dir diskd /squidcache/cache/6 7000 64 256 Q1=64 Q2=72 request_body_max_size 0 KB visible_hostname server.domain.com.br # Determinando o diretorio onde estara armazenado o cache das paginas cache_log /var/log/squid/cache.log cache_access_log /var/log/squid/access.log cache_store_log /var/log/squid/store.log hierarchy_stoplist cgi-bin ?
