Out[1]=

Define handler:

In[2]:=
AbsoluteTiming[imgStr = ExportString[ Plot[{ Sin[x], Cos[x], Sin[2 x], Cos[2 x], Sin[2 x * Cos[x]], Cos[2 x * Sin[x]], BesselJ[1, x], BesselJ[2, x], BesselJ[3, x], BesselJ[4, x] }, {x, 1, 10}, Filling -> Bottom, ImageSize -> Large, PlotTheme -> "Detailed", PlotPoints -> 1200 ], "SVG" ]; ]
Out[2]=
In[3]:=
AbsoluteTiming[ resp = StringToByteArray[ "HTTP/1.1 200 OK\r\nConnection: Keep-Alive\r\nContent-Type: text/xml\r\nContent-Length: " <> ToString[StringLength[imgStr]] <> "\r\n\r\n" <> imgStr]; ]
Out[3]=
In[4]:=
Length[resp]
Out[4]=
In[5]:=
hist = {}
Out[5]=
In[6]:=
handler[assoc_Association] := Module[{client, request, response, img}, client = assoc["SourceSocket"]; request = ByteArrayToString[assoc["DataByteArray"]]; response = resp; AppendTo[hist, assoc]; BinaryWrite[client, response]; ]

Go to http://localhost:8000:

In[7]:=
SystemOpen["http://localhost:9000"]

Now you can Delete SocketListener:

In[8]:=
DeleteObject[clistener]
Out[8]=

Build library (5) 

Library source file:

In[9]:=
$libSrc = File[FileNameJoin[{NotebookDirectory[], "Source", "socket_listener.c"}]]
Out[9]=

Library output directory:

In[10]:=
$libDir = FileNameJoin[{NotebookDirectory[], "LibraryResources", $SystemID}]
Out[10]=

Create if does not exist:

In[11]:=
If[! FileExistsQ[$libDir], CreateDirectory[]];

Get compiler:

In[12]:=
Get["CCompilerDriver`"];

Create dynamic lbrary:

In[13]:=
CreateLibrary[$libSrc, "socket_listener", "TargetDirectory" -> $libDir];
