400 bad request request header or cookie large

here is "keep-alive", or the request uses HTTP 1.1 (HTTP 1.1 performs a persistent connection by default), it can take advantage of the advantages of persistent connections, when a page contains multiple elements (such as an applet or image), the download time is significantly reduced. To achieve this, the servlet needs to send a Content-Length header in the response. The simplest method is to write the co

information, which typically occurs in an answer to the Www-authenticate header sent to the server. Connection: Indicates whether a persistent connection is required. If the servlet sees the value here as "keep-alive", or sees the request using an HTTP 1.1 (HTTP 1.1 is persistent by default), it can take advantage of the persistent connection, when the page contains multiple elements (such as applets, pict

Php views the request header information to obtain the remote image size. To obtain the size of a remote image, a common practice is to first retrieve the content of the remote image and use strlen to calculate the length. in this way, you need to download the image, then, if you want to obtain the size of a remote image, a common practice is to first retrieve the content of the remote image and use strlen

Php uses the fsockopen method to obtain the header information. If an image is requested, the Content-Length indicates the image size. if you want to obtain the size of a remote image, A common practice is to retrieve the content of a remote image and calculate the length using strlen. this method requires downloading the image before calculating it. If the image size is large, network transmission takes a

If you want to get the size of a remote picture, it's a common practice to get the contents of the remote picture back and then use strlen to compute the length, which requires downloading the pictures before you can compute them. If the picture is very large, then the network transmission will take a lot of time, the efficiency is obviously low. The author provides a method to improve efficiency, mainly using HTTP

I believe we all know that the common request way is "Get" and "post", then the following to explore the next get and post are what fun places, or talk, firstI enter www.baidu.com and will find the following request and response information.1: "Request Header":First line: get/http/1.1There are three messages in this: ①

Take the watercress as an example, visit https://www.douban.com/contacts/list to see who you care about, and log in to view it.If you use the Requests.get () method to get this HTTP, no login can only catch a login interface, so we have to use Python to log into the site to crawl the desired page.An easy way to do this is to log in on your browser and then use the method (chrome as an example) to find your own cookie and user-agent, Then use Python to

); // when used up, remember to turn it off. Alternatively, use the get_headers function to get all the headers sent by the server in response to an HTTP request. The example code is as follows: In php, if we want to obtain data, simulate login, POST data, and other functions, we must first think of the curl function, this function is convenient and practical and supports multithreading. the following example is provided. if you are interested, refer

the file.Browser encodingWhen submitting a request to the server, the browser needs to submit a large amount of data to the server side, and before submission, the browser needs to be encoded in a way that is recognizable by the server side, which is simple for normal form data, and the encoded result is usuallyThe form of field1=value2field2=value2, such as the specific rules of this code can be found in

Remove the events in the original init and add our own events. the key steps have finally been completed, here, we want to intercept HTTP requests, obtain file information, obtain upload progress, and other events. 3.1 determine whether a file is uploaded because the form

From: http://www.cnblogs.com/stg609/archive/2008/08/03/1258898.html I am sorry to continue to complete this article after so long, because I found that the upload was unstable during later debugging, so after several days of debugging, the current test is basically no problem. Review the previous article to learn about the following: After the HTTP request flow arrives at the server, the IIS process or HTTP. sys receives and calls ASP. net ISAPI

The $.get and $.post methods of JQ are not accessible across domains. $.getjson let us see the dawn of Hope,However, one thing that is not enough is that this is a get method, the parameters passed are limited, the maximum is not more than 2,083 characters.But there is a solution to the problem, and the analysis concludes that the solution is as follows:A.com uses $.getjson to send a request to B.Com, and at the same time, A.com put the required conte
