    <p>I am building a web server in python using the select() function - I/O multiplexing. I am able to connect to multiple clients which in my case are web browsers (safari, chrome, firefox) and accept each clients HTTP 1.1 GET requests. Once i receive the request I return the html page content to the the browser where the html page is displayed.</p> <p>The problem i am getting is when i try to keep the connection open for a while. I realized that i am not able to display anything in the browser until i close the connection using fd.close().</p> <p>Here is the function i am using to accept and respond to the browser request. The problem is after i use fd.sendall(), i dont want to close the connection but the page wont display until i do. Please help! Any help or suggestion is appreciated.. </p> <pre><code>def handleConnectedSocket(): try: recvIsComplete = False rcvdStr = '' line1 = "HTTP/1.1 200 OK\r\n" line2 = "Server: Apache/1.3.12 (Unix)\r\n" line3 = "Content-Type: text/html\r\n" # Alternately, "Content-Type: image/jpg\r\n" line4 = "\r\n" line1PageNotFound = "HTTP/1.1 404 Not Found\r\n" ConnectionClose = "Connection: close\r\n" while not recvIsComplete: rcvdStr = fd.recv( 1024 ) if rcvdStr!= "" : # look for the string that contains the html page recvIsComplete = True RequestedFile = "" start = rcvdStr.find('/') + 1 end = rcvdStr.find(' ', start) RequestedFile = rcvdStr[start:end] #requested page in the form of xyz.html try: FiletoRead = file(RequestedFile , 'r') except: FiletoRead = file('PageNotFound.html' , 'r') response = FiletoRead.read() request_dict[fd].append(line1PageNotFound + line2 + ConnectionClose + line4) fd.sendall( line1PageNotFound + line2 + line3 + ConnectionClose + line4 + response ) # fd.close() &lt;--- DONT WANT TO USE THIS else: response = FiletoRead.read() request_dict[fd].append(line1 + line2 + line3 + ConnectionClose + line4 + response) fd.sendall(line1 + line2 + line3 + line4 + response) # fd.close() &lt;--- DONT WANT TO USE THIS else: recvIsComplete = True #Remove messages from dictionary del request_dict[fd] fd.close() </code></pre> <p>The client (browser) request is in HTTP 1.1 form as shown:</p> <pre><code>GET /Test.html HTTP/1.1 Host: 127.0.0.1:22222 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8) AppleWebKit/536.25 (KHTML, like Gecko) Version/6.0 Safari/536.25 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us Accept-Encoding: gzip, deflate Connection: keep-alive </code></pre>

    1. COYour indentation is a little mixed up (look at your `while not recvIsComplete` part) - also `file` (`open` is recommended instead) was deprecated so I don't think you need a `python-3.x` tag, so I've removed it

    2. COi added python 3.x because i think this problem is not only python 2.7 related. I am looking for suggestions and ANY advice on how i can fix this. Even a python 3.x person can suggest a solution.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
