http-headers

问题 If i have an applicataion requesting a service, is it possible for the web service to determine the name of the application or does this have to be sent within the request? 回答1: You can use the UserAgent header of the HTTP request if the application sets it. 回答2: This would have to be sent in the request, or in the headers, as the above post suggests. There is no Internet standard as to what an "application" is, so there's certainly no standard for "application name". 来源： https:/

问题 So I'm trying to iterate over Response.Headers for a custom caching job, but I'm getting the following error when I touch the thing: This operation requires IIS integrated pipeline mode It this possible to do in IIS6? Is there a workaround? var allHeaders = HttpContext.Current.Response.Headers; // error thrown as soon as it's accessed 回答1: AFAIK you cannot access the HTTP response headers unless you are running in integrated mode because they are sent by the server at a later stage of the

问题 So I saw this great post Error: Can't set headers after they are sent to the client , but still do not understand, what is wrong with my Headers section, because when I changed it from my commented out wrong type into two separated sections: app.use(doesNotModifyBody); app.use(doesModifyBody); (like in answer above) it does not work normally.

问题 I would like to get the HTTP error code while opening a remote file via fopen() function. I have the following code: $remote = fopen ($url, "rb"); If the URL is fine, the file would be opened. Otherwise, fopen triggers an error message similar to Warning: fopen(url): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found . I know that adding a @ before the fopen() would suppress the error message, but how can I get the http error code instead? Here, I want to get HTTP/1.1 404 Not

问题 I have asked this question today already but this time I want to know if I can achieve this via PHP since Javascript wasn't up to it. I have a link to a file on another server. If i provide this link to my users the headers are pushed out to download that file from that server. Is there a way for me to capture those headers and file and redirect the download to the user? I would like to do this so that I can change the filename of the download since it is always 'file.zip'. Is this possible
