在进行svn update时，总是出现如下异常：
svn: Server sent unexpected return value (413 Request Entity Too Large) in response to REPORT request for '/svn/!svn/vcc/default'
“413 Request Entity Too Large”是由web server发出来的，表示HTTP请求中的内容太大，撑爆掉了。
我的Web Server是“Apache Http”，所以需要在httpd.conf中加入如下配置：
LimitXMLRequestBody 0
LimitRequestBody 0
参照：http://httpd.apache.org/docs/2.2/mod/core.html#limitxmlrequestbody
LimitXMLRequestBody Directive
| Description: | Limits the size of an XML-based request body |
|---|---|
| Syntax: | LimitXMLRequestBody bytes |
| Default: | LimitXMLRequestBody 1000000 |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | All |
| Status: | Core |
| Module: | core |
Limit (in bytes) on maximum size of an XML-based request body. A value of 0 will disable any checking.
Example:
LimitXMLRequestBody 0
LimitRequestBody Directive
| Description: | Restricts the total size of the HTTP request body sent from the client |
|---|---|
| Syntax: | LimitRequestBody bytes |
| Default: | LimitRequestBody 0 |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | All |
| Status: | Core |
| Module: | core |
This directive specifies the number of bytes from 0 (meaning unlimited) to 2147483647 (2GB) that are allowed in a request body.
The LimitRequestBody directive allows the user to set a limit on the allowed size of an HTTP request message body within the context in which the directive is given (server, per-directory, per-file or per-location). If the client request exceeds that limit, the server will return an error response instead of servicing the request. The size of a normal request message body will vary greatly depending on the nature of the resource and the methods allowed on that resource. CGI scripts typically use the message body for retrieving form information. Implementations of the PUT method will require a value at least as large as any representation that the server wishes to accept for that resource.
This directive gives the server administrator greater control over abnormal client request behavior, which may be useful for avoiding some forms of denial-of-service attacks.
If, for example, you are permitting file upload to a particular location, and wish to limit the size of the uploaded file to 100K, you might use the following directive:
LimitRequestBody 102400
