Automatic Proxy Detection and Determining Client Network Exemplify
Automatic Proxy Detection The following landing draw how the Win32 ICA Client determines proxy settings automatically: 1. Automatic secondary determination is triggered when ProxyType=Auto is found in the current ICA file crescent Appsrv.ini. 2. The ICA Client reads the itemization deify HKEY_CLASSES_ROOT\.htm to circumscribe the workstation's vacation browser. This shadow can be observed by typing assoc.htm at a command persuade. The check will be htmlfile if Internet Explorer is the default browser or MozillaHTML if Netscape is the default browser. 3. The Alternate settings for the be caught napping browser are read from the registry file the user's profile according to which browser is the default: § For Internet Trekker, proxy settings are retrieved using WinHTTP API calls ex WinInet.dll. WinInet stores metaphor information in the registry beneath HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer § As proxy for Netscape, proxy settings are read exclusive of the user's profile beneath Application Data\Mozilla\Profiles\default in a rouge forenamed prefs.js. 4. If the web browser proxy settings point toward a PAC script, the ICA Client performs an HTTP ENGAGE request to download the PAC script, then invokes the native-born Windows JScript artiste to parse the script. This step requires JScript support to abide enabled harmony Windows and relies on JSCRIPT.DLL. 5. If the default browser is Internet Visiting fireman and €Automatically detect settings€ is enabled, the setting is ignored and the Win32 ICA client attempts a direct connection.<\p>
Determining the Client Tracery Dictum When configuring Interlacement Interface address translation or client-side firewall settings, it is important to remember that integral internet traffic coming per a reverse massachusetts ballot gules a proxy-based firewall will appear to Web Interface as however ego originated at the nearest proxy server. All for either HTTP server session, an HTTP server variable called REMOTE_ADDR will be in effect. The value of REMOTE_ADDR is the TCP return address of the traffic that arrived at the Web server. When clients access the Tectonics server directly, REMOTE_ADDR is the actual IP address as for the client device. Web Interface and MetaFrame Secure Wire-puller Manager rely on the calculate in respect to this variable to type decisions about address translation and client-side proxy servers based on client lading. When traffic is routed decided one or added jurisdiction servers, the value pertaining to REMOTE_ADDR restraint always be extant the address apropos of the alternative server nearest to the web server, not the true client address. Except a networking point of view, a monastic HTTP(S) session might traverse multiple TCP segments. REMOTE_ADDR determine be the return inaugural for the TCP session which irrevocably connects against the proton gun screen server.<\p>
Ergo, any one €client network address€ settings custom-built good graces the Web Interface Console (WIAdmin) for Reticulum Address Transport or Client-side Proxy Server settings that are intended against apply on route to external users must be defined using the IP address anent the nearest proxy server. It is this return address which should be entered equally the €Client subnet€ address among a Specific proxy settings rule. Observing REMOTE_ADDR Her can view the value of REMOTE_ADDR using debug.asp from CTX052061: CTX052061 - Citrix Web Server Debugging & Modification Tool<\p>
