HTTP(S)/WebDAV Preferences

To set the HTTP(S)/WebDAV preferences, open the Preferences dialog box and go to Network Connection Settings > HTTP(S)/WebDAV. The following options are available:

Internal Apache HttpClient Version - Oxygen XML Developer uses the Apache HttpClient to establish connections to HTTP servers. To enable Oxygen XML Developer to benefit from particular sets of features provided by different versions, you may choose between v3 and v4.
Note: For a full list of features, go to http://hc.apache.org/httpclient-3.x/ and http://hc.apache.org/httpcomponents-client-ga/
Maximum number of simultaneous connections per host - Defines the maximum number of simultaneous connections established by the application with a distinct host. Servers might consider multiple connections opened from the same source to be a Denial of Service attack. You can avoid that by lowering the value of this option.
Note: This option accepts a minimum value of 5.
Read Timeout (seconds) - The period in seconds after which the application considers that an HTTP server is unreachable if it does not receive any response to a request sent to that server.
Enable HTTP 'Expect: 100-continue ' handshake for HTTP/1.1 protocol - Activates Expect: 100-Continue handshake. The purpose of the Expect: 100-Continue handshake is to allow a client that is sending a request message with a request body to determine if the origin server is willing to accept the request (based on the request headers) before the client sends the request body. The use of the Expect: 100-continue handshake can result in noticeable performance improvement when working with databases. The Expect: 100-continue handshake should be used with caution, as it may cause problems with HTTP servers and proxies that do not support the HTTP/1.1 protocol.
Use the 'Content-Type' header field to determine the content type - When checked, Oxygen XML Developer tries to determine a resource type using the Content-Type header field. This header indicates the Internet media type of the message content, consisting of a type and subtype, for example:
```
Content-Type: text/xml
```
When unchecked, the resource type is determined by analyzing its extension. For example, a file ending in .xml is considered to be an XML file.
Automatic retry on recoverable error - If enabled, if an HTTP error occurs when Oxygen XML Developer communicates with a server via HTTP, for example sending / receiving a SOAP request / response to / from a Web services server, and the error is recoverable, Oxygen XML Developer tries to send again the request to the server.
Automatically accept a security certificate, even if invalid - When enabled, the HTTPS connections that Oxygen XML Developer attempts to establish will accept all security certificates, even if they are invalid.
Important: By accepting an invalid certificate, you accept at your own risk a potential security threat, since you cannot verify the integrity of the certificate's issuer.
Encryption protocols (SVN Client only) - this option is available only if you run the application with Java 1.6 or older. Sets a specific encryption protocol used when a repository is accessed through HTTPS protocol. You can choose one of the following values:
- SSLv3, TLSv1 (default value);
- SSLv3 only;
- TLSv1 only.
Lock WebDAV files on open - If checked, the files opened through WebDAV are locked on the server so that they cannot be edited by other users while the lock placed by the current user still exists on the server.
