BOA thttpd goahead

BOA has complete functions, so many functions of embedded applications are redundant (such as virtual host), with a larger memory usage.
Thttpd has fewer functions and is easy to implement. It uses less memory and is more convenient to expand.
SHTTPD functions are comprehensive, but it is not stable enough to process binary data, and there are exceptions.
Light-HTTPd, Apache is a heavyweight server that is mature, stable, and bulky. It can be used in complicated embedded applications.
Goahead is a dedicated webserver. Most of its functions serve its own goform function and
ASP/JavaScript functions. The last version 2.1.8 still has many bugs (see below)
The mini-httpd and thttpd are the same and have almost identical functions.

BOA defects:
(1) The CGI parsing header is not provided for processing.
Can easily modify. http://bbs.chinaunix.net/viewthread.php by this address? Tid = 824840
(2) Use temporary file buffering for post data. For small system systems that cannot create temporary files, you need to manually change thisCode.
Many people report that data cannot be post during transplantation. This is the reason.

Thttpd defects:
(1) The support for cgi1.1 standards is incomplete (with little influence) and other HTTP header processing required by the Protocol is not provided,
Applications such as if-modified-since and accept-languageProgramIt cannot be received.
(2) directly using socket to rewrite the CGI application will lead to a large amount of post data (such as uploading files ),
The CGI application cannot respond to the browser without reading all the post data.
(3 )...

Goahead defects:
(1) dedicated, such as goform and ASP statements provided by OSS.
(2) CGI has many bugs in binary output.
(3) to process a single task, the platform uses a delay round-robin receiving queue, Which is inefficient at processing.
(4) other bugs may not be listed in the list. You need to set them one by one during porting.

Personal opinion, for reference only.

In uClinux, there are three main Web servers: httpd, thttpd, and boa. Httpd is the simplest Web server. It has the weakest function, does not support authentication, and does not support CGI. Both thttpd and BOA support authentication, CGI, and other functions.
