Monitoring Period: The server considers only the bad requests that are generated by a client during the last Monitoring Period to decide whether to ban it or not. #ABYSS WEB SERVER ERROR 405 CODE#A request that results in a reply which HTTP status code is 403, 404, 405, or 408 is counted as half a bad request. A request that results in a reply which HTTP status code is 400 or 401 is counted as a bad request. Fill this table with trusted IP addresses only.īad Requests Count Before Banning: The number of tolerated bad requests before considering the client as attempting to hack the server. Refer to " IP Addresses and Ranges Format" appendix for more information about the IP addresses and ranges. The displayed dialog is made of the following items:Įnable Automatic Anti-Hacking Protection: Check it to enable the automatic anti-hacking protection system.ĭo not Monitor Requests from: This table contains the IP addresses or IP address ranges that should not be protected against hacking. This information helps the browser to know what kind of file it is (HTML, ZIP, JPEG image, etc…)Īnd what to do with it (display it, save it on the disk, launch a configured application to read it, etc…).Ībyss Web Server comes with a list of common MIME types used as a default.Ī MIME Type has the format type/subtype and is associated to one or more extensions separated by spaces.įigure 4-6. When the server sends a document to a browser, it also sends its MIME type. Note that when the Host value is restored, the request will be normally processed and checked against the host names of each of the hosts managed by the server. X-Forwarded-Host and X-Host are the most common header names used for that purpose. X-Forwarded-For and X-Real-IP are the most common ones widely used in reverse proxies.įorwarded-Host Headers: The names of the headers that should be checked for the original Host header value as the client sent it to the frontal reverse proxy. Proxies: The list of IP addresses of computers which are recognized as reverse proxies and for which the server should act as a transparent back-end.įorwarded-For Headers: The names of the headers that should be checked for the original IP of the reverse proxy client. This dialog contains the following fields: to control the back-end operation support settings. This can help make the frontal reverse proxy completely transparent to Web applications running on Abyss Web Server and to the logging taking place on it. Do not decrease it too much if you have content heavy pages.īack-end Operation Support: When Abyss Web Server is used as a back-end for another reverse proxy, it can be configured to restore the original IP address of the reverse proxy client and other details before processing the request. A stream is almost always associated with a HTTP request. Maximum Concurrent Streams Count: The maximum number of streams that could be multiplexed over each HTTP/2 connection. It is recommended to not alter its default value unless you are fully aware of how it affects the latency and the quality of service of HTTP/2 connections. Changing it impacts initial buffer sizes on both the client and the server. Initial Window Size: The initial connection flow-control window size in bytes. The associated dialog has the following fields:ĭisabled: A global switch for disabling HTTP/2 support in all hosts and in the console. HTTP/2 Parameters: HTTP/2 support can be configured by pressing Edit. Only HTTP/1.1 and some HTTP/1.0 compliant browsers can benefit Keep-Alive Requests: The maximum number of requests that can be served over The displayed dialog has the following fields: HTTP/1.1 Parameters: It is possible to fine tune parameters of HTTP/1.1 connections by pressing Edit. Requests which exceed this limit are refused and a HTTP error 413 (Request Entity Too Large) is reported to the client. Maximum length of the HTTP request headers: The maximum length in bytes of all the HTTP request headers. Requests which do not respect this limit are refused and a HTTP error 414 (Request-URI Too Long) is reported to the client. Maximum length of the HTTP request line: The maximum length in bytes of the HTTP request line. to access the advanced parameters dialog. Maximum Simultaneous Connections: The maximum number of connections the server canĪdvanced Parameters: Press Edit. Timeout: How many seconds the server waits for an inactive It is used as the base path for all relative real paths in the configuration. Where Abyss Web Server executable is installed. Server Root: The root path of the web server. The dialog includes the following fields:
