WEB Get server info
WEB Get server info {( withCache )} -> Function result
| Parameter | Type | Description | |
|---|---|---|---|
| withCache | Boolean | 🡒 | True to return the Web cache description. Otherwise (default), the cache description is not returned. |
| Function result | Object | 🡐 | Information on the running Web server and SOAP server |
Description
The WEB Get server info command returns an object containing detailed runtine information on the 4D Web server current session. Returned information include the SOAP server.
Note: This command returns runtime information, i.e. actual parameters used by the Web server. These parameters can differ from those returned by the WEB GET OPTION command since they depend on system settings, available resources, etc.
By default, the command does not return the "cache" property, since it can be a very large. However, if you want to know the cache contents, pass True in the withCache optional parameter.
The returned object contains the following properties (property names are case sensitive):
| Property | Value type | Description |
|---|---|---|
| started | Boolean | True if the http server is started, False otherwise |
| uptime | Number | Time elapsed since last startup of the http server |
| httpRequestCount | Number | Number of http hits received by the server since it was started |
| startMode | String | "automatic" if “Launch Web Server at Startup" is checked, otherwise "manual". |
| SOAPServerStarted | Boolean | True if the SOAP server is started, False otherwise |
| cache | Object | This property is included only if the withCache parameter is True. Describes the contents of the web server cache (see cache property below) |
| security | Object | Current status of the various security options |
| cipherSuite | String | Cipher list used by 4D for the secure protocol (corresponds to the SSL cipher list database parameter) |
| HTTPEnabled | Boolean | True if HTTP is enabled |
| HTTPSEnabled | Boolean | True if HTTPS is enabled |
| HSTSEnabled | Boolean | True if HSTS is activated on the server |
| HSTSMaxAge | Number | Maximum age (in seconds) for HSTS. The default is 2 years (63,072,000 seconds). |
| minTLSVersion | String | Minimum TLS version accepted for connections (corresponds to the Min TLS version database parameter) |
| openSSLVersion | String | Version of the used OpenSSL library |
| perfectForwardSecrecy | Boolean | True if PFS is available on the server, False otherwise |
| options | Object | Current status of various standard web server options |
| CORSEnabled | Boolean | True if the CORS service is enabled on the server, False otherwise (default) |
| CORSSettings | Collection | Collection of CORS objects defining the list of allowed host(s) and method(s) (see Web CORS settings web option) |
| webCharacterSet | String | Character set name (corresponds to the Web character set web option) |
| webHTTPCompressionLevel | Number | Compression level for compressed HTTP exchanges (corresponds to the Web HTTP compression level web option) |
| webHTTPCompressionThreshold | Number | Compression threshold (corresponds to the Web HTTP compression threshold web option) |
| webHTTPSPortID | Number | TCP port number used by the Web server for secure connections (corresponds to the Web HTTPS port ID web option) |
| webInactiveProcessTimeout | Number | Not significant in scalable web sessions mode, see Web Sessions Management (Legacy). Life duration of the inactive session processes (corresponds to the Web inactive process timeout web option) |
| webInactiveSessionTimeout | Number | Not significant in scalable web sessions mode, see Web Sessions Management (Legacy). Life duration of the inactive sessions (corresponds to the Web inactive session timeout web option) |
| webIPAddressToListen | Collection | IP address(e) in the defined "format" on which the web server receives http requests (corresponds to the Web IP address to listen web option) |
| webMaxConcurrentProcesses | Number | Not significant in scalable web sessions mode, see Web Sessions Management (Legacy). Maximum number of concurrent web processes (corresponds to the Web max concurrent processes web option) |
| webPortID | Number | TCP port used by the Web server (corresponds to the Web port ID web option) |
4D Server: The command returns information about the local Web server. If you want to monitor the 4D Server web server from a remote 4D, you need to apply the "Execute on server" property to the method.
cache property
If you pass true in the withCache parameter, the command returns the "cache" object property with the following contents:
| Property name | Value type | Description |
|---|---|---|
| cacheUsage | Number | Cache usage rate |
| numOfLoads | Number | Number of loaded objects |
| currentSize | Number | Cache current size |
| maxSize | Number | Cache maximum size |
| objectMaxSize | Number | Maximum size of objects loadable in the cache |
| enabled | Boolean | true if the web server cache is enabled |
| nbCachedObjects | Number | Number of objects in the cache |
| cachedObjects | Collection | Collection of objects in the cache. Each cached object is defined by different properties (url, mimeType, expirationType, lastModified, etc.) |
Example
After you execute the following code:
$webServerInfo:=WEB Get server info(True)
... $webServerInfo will contain for example:
{ "started": true, "uptime": 40, "SOAPServerStarted": true, "startMode": "manual", "httpRequestCount": 0, "options": { "CORSEnabled": false, "CORSSettings": null, "webCharacterSet": "UTF-8", "webHTTPCompressionLevel": 1, "webHTTPCompressionThreshold": 1024, "webHTTPSPortID": 443, "webIPAddressToListen": ["192.168.xxx.xxx"], "webInactiveProcessTimeout": 28800, "webInactiveSessionTimeout": 28800, "webMaxConcurrentProcesses": 100, "webPortID": 80 }, "security": { "HTTPEnabled": true, "cipherSuite": "ECDHE-RSA-AES128-GCM-SHA256:...:CAMELLIA128-SHA", "openSSLVersion": "OpenSSL 1.0.2h 3 May 2016", "perfectForwardSecrecy": true, "minTLSVersion": "1.2" }, "cache": { "cacheUsage": 1, "numOfLoads": 24, "currentSize": 154219, "maxSize": 10485760, "objectMaxSize": 524288, "enabled": true, "nbCachedObjects": 23, "cachedObjects": [ {...},{...} ] }}
