Unable to access a website which uses a non-standard port which is other than the default port 80 for HTTP or port 443 for HTTPS.

Sometimes, you might come across a website that uses port numbers other than 80 or 443.

Example: , where 123 is the port number and is different than 80 or 443.

Port 80 is the default for HTTP protocol while port 443 is the default for HTTPS protocol and are usually omitted from the URL.

Internet Explorer: "This page can't be displayed."



Client Site Proxy



The Web service is not able connect to non-standard ports other than port 80 and 443, therefore it is unable to scan contents for websites that are using custom ports.

The only ports available for scanning are port 80 (HTTP) and port 443 (HTTPS).



If you are using our Client Site Proxy, you can bypass the non-standard ports and set up a direct connection.
If the bypass has been implemented, any traffic on the bypassed ports would not be scanned by our Web services.
If you wish to bypass the website that is on a non-standard port, please enter the following in C:\ClientSiteProxy\etc\squid.conf

acl Bypass_Ports port 8080 9090 # example bypased ports ; change this to your preference
http_access allow Bypass_Ports
always_direct allow Bypass_Ports

Then, configure the bypassed website according to TECH237276
