Network Tab

This is where you set up options that affect the functions of HTML Validator that require a network connection.

HTTP Proxy

Enable HTTP proxy - Check this box if you want to use an HTTP proxy for HTTP requests. Some users may be required to use a proxy for any HTTP request. In this case, you must enable the HTTP proxy by checking this box and also enter the necessary proxy information. Without the correct proxy information, the functions of HTML Validator that require making HTTP requests may not function (such as opening documents from the web and checking to see if you are using the latest version of HTML Validator). This option is not enabled by default.
Proxy - Enter the address of the HTTP proxy.
Port - Enter the port of the HTTP proxy. The default is port 80.
Username - If the proxy requires you to log in, enter the username to log in with.
Password - If the proxy server requires a password, enter the password to use. Note that proxy information, including the password, is not stored securely on your computer.

Link Checking (Pro, Std, Lite)

HTTP Timeout - When using the HTTP protocol (such as when link checking), this option specifies a time to wait in seconds before failing. For instance, if a link check cannot complete within this time period, then the link check will automatically abort and fail with a "time out" error. Valid values are 1 or more second. The default value is 30 seconds.
Max simultaneous link checks - Specify the number of simultaneous link checks HTML Validator will perform to try to improve performance. Valid values are 1 to 200. Higher values may have side effects and may put a heavy load on a server if too many links on the same server are checked at the same time. A high value could also cause incorrect results and unnecessary timeouts. If you believe that the link check results are incorrect (incorrect results would most likely be in the form of correct links being flagged as bad or broken), then you may want to try lowering this value. The default value is 15.
Redirected links - Specify whether redirected links should be OK, warnings, or errors. Redirected links are those that when requested from the server, the server redirects the client to another URL. If set to "Error", then redirected links will be preceded by a red icon in the Links tab of the Results Window. If set to "Warning", then a yellow icon will be used. If set to "OK", then a green icon will be used. The default is to treat redirected links as warnings. (New v6.50)
Disable email address syntax checking - Check this box so that anytime an email address is checked for correct Internet email address syntax, the address is accepted as a valid address. This box should only be checked when you are not using Internet formatted email addresses. An example of an Internet formatted email address is username@domain.com. An example of a non Internet formatted email address is John Doe. This option is not enabled by default. Therefore, the default is to check email address syntax. (New v4.50)
Case sensitive link checking - Check this box to enable case sensitive link checking for local file and local folder links. Due to technical reasons, this does not apply to other types of links such as HTTP links. This option is useful if the web document will be hosted on a server where filenames are case sensitive, such as a Unix or Linux based server. Even if the web site will be hosted on a Windows based server (which is not case sensitive), it is still a good idea to make sure that the case matches. If a local file or local folder link is valid except that its case does not match, then the link checker will generate an error for the link and the link status will be "Incorrect Case". This option is enabled by default. (New v6.50)

Link Cache (Pro, Std, Lite)

HTML Validator keeps a "link cache" in memory for the duration of program execution (the cache is automatically reset when HTML Validator is terminated or reloaded). When a link is checked, the result is stored in the cache so that the link does not have to be checked again.

Reset - Clears everything in the link cache. All links and link checking results are cleared from memory so that any new links will have to be added to the link cache again and be rechecked.
