Forgot to mention that they use Apache server in tandem with Windows IIS.

Subject: [users@httpd] Very slow Apache proxy server under IE

I have the following architecture: a JSP page with JavaScript client code, the backend is a JAVA class that gets data from an Oracle database. The whole app runs on a WebLogic 10 server. It works fine in my development environment and also on the client's internal network. However, the client has set-up an Apache proxy server to give external users access to the application as well. Access to the application from the outside is implemented like this:

	1. external access to app is done via Apache Webserver on border server
	2. request from external user is accepted by apache via HTTPS
	3. forwarder in Apache sends the request to inside network

So, for these external users the page is very slow, it takes about 5 minutes to load. However, it is only slow under Internet Explorer 8 (and 9). It works fine under Chrome and FireFox. The following modules are installed on the Apache proxy server:

LoadModule access_module modules/mod_access.so LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule asis_module modules/mod_asis.so LoadModule auth_module modules/mod_auth.so LoadModule auth_anon_module modules/mod_auth_anon.so LoadModule auth_dbm_module modules/mod_auth_dbm.so LoadModule auth_digest_module modules/mod_auth_digest.so LoadModule autoindex_module modules/mod_autoindex.so LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule cgi_module modules/mod_cgi.so LoadModule dav_module modules/mod_dav.so LoadModule dav_fs_module modules/mod_dav_fs.so LoadModule dir_module modules/mod_dir.so LoadModule env_module modules/mod_env.so LoadModule expires_module modules/mod_expires.so LoadModule file_cache_module modules/mod_file_cache.so LoadModule headers_module modules/mod_headers.so LoadModule imap_module modules/mod_imap.so LoadModule include_module modules/mod_include.so LoadModule info_module modules/mod_info.so LoadModule isapi_module modules/mod_isapi.so LoadModule log_config_module modules/mod_log_config.so LoadModule mime_module modules/mod_mime.so LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule negotiation_module modules/mod_negotiation.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so LoadModule speling_module modules/mod_speling.so LoadModule status_module modules/mod_status.so LoadModule unique_id_module modules/mod_unique_id.so LoadModule userdir_module modules/mod_userdir.so LoadModule usertrack_module modules/mod_usertrack.so LoadModule vhost_alias_module modules/mod_vhost_alias.so LoadModule ssl_module modules/mod_ssl.so LoadModule weblogic_module modules/mod_wl_20.so

Does anybody have any idea why it would be so slow under IE?

Thanks.
